House Rule Rebuttal:  Back Shields
Recently in a 3.5 game, a player proposed a house rule to me that he would like to incorporate in the game:  back shields.  His proposed rule was that a character could wear a shield on their back, which wouldn't add a shield bonus but would negate an opponent's flanking bonus.  I argued that, while I appreciate the historical verisimilitude of such a style (we both do Dagorhir, a foam LARP, which includes back shields, and I've done live-steel as well), I felt that the idea was unbalancing for inclusion, namely in that it did not have enough of a drawback.  To whit:

I feel that in the set-up of 3.5, a character's fighting style comes with certain perks and drawbacks.  Namely, characters who choose two-weapon or two-handed weapons are substituting offense for defense.  This ends up balancing out, more or less.  I feel that adding back shields adds a benefit without a concomitant drawback.  His argument is that there *is* a drawback, in that you have a shield that's only useful in a given situation (being flanked), and you still take the armor penalty for using that shield.  I countered that a bonus that isn't *as good* as a regular bonus (i.e. using a shield) is still an added bonus not built into the balance of play.

Furthermore, I can't see justifying negating the +2 flanking bonus without also negating any precision attacks (i.e. sneak attack) derived from flanking.  He argued that he'd be fine with granting the flanking *bonus* negation, but not the flanked *status* (thus granting Rogues and other characters their precision-based attacks).  For purposes of realism I couldn't see negating one without the other:  if you have a large plank of wood or metal strapped to your back, it's going to fairly effectively block most incoming blows, at least to the point where the kind of strategic placing of sneak attack wouldn't be feasible.  We argued what the difference is between a shield gripped in the hand and such a shield on the back:  namely that a back shield isn't moving, whereas a hand-held shield does, and one can feint around it, etc.  While one could arguably reach around to strike their opponent, again it stretches the feasibility of the accuracy of precision-based damage.  I'm more concerned with how this would affect the party's precision attacker, who would now be up against NPCs who (with any intelligence) would be using this fighting style to negate his sneak attacks.

Long story short, he continued to argue that his proposal of a shield that doesn't fully function as a shield yet adds to the defensive capabilities of two-handed characters is enough of a drawback to warrant their use.

To put in further perspective, we have a party none of whom use shields:  a two-weapon fighter, a pole-fighter, an archer, and my friend who uses a single sword (and gets bonuses with various feats and such).  So I feel this greatly skews in their favor.

Well, I agree that getting +2 bonus (or in some cases perhaps more) vs flanking attacks seems like a relatively big deal, at least anytime you are being flanked.  I agree that mechanically, it makes more sense not to split precision damage from the flanking bonus, but, admittedly one could argue someone can stab around the sheild.  However, that is also very true for the original attacks too.  One could also point out that a full plate, will basically have a sheet of steel behind it, why doesn't simply wearing heavy armor aleviate the flanking bonus?  (basically, the bonus is not being able to be aware of what is going on all the way around you)

Asuming you are talking about a heavy sheild, giving a +2 AC vs flanking attack, means you have an absolutely fully effective shield being actively projected out your back, as it is getting a full benefit.  I'd be more inclined to believe it would have to grant 'less' than full bonus, meaning none, for a light or buckler (since they are normally only 1) and perhaps a +1 bonus with a heavy sheild on ones back.  Keep in mind, a flanking attack need not strike them in their back, it can just as easily hit them in the leg, arms, or head, just like any other attack.  It just is easier to land some sort of hit, as the person is having to shift their awareness around to try to keep track of their opponents.

Or, if they insist that they should get their bonus, and you decide to let them have it.  Don't forget, if they are effectively 'back-wielding' a shield, they should be inhibited by wearing it.  This means applying the shields armor check penalty.

Next point out, unless they have some sort of feat granting them EXTRA training to effectively use a 'back sheild' with expertise, they are non-proficient with it.  That of course means they well take a penalty equal to the shield's Armor Check Penalty to all attack rolls, STR, and DEX based skill checks.

It could be amusing to consider someone suggesting they are going to strap a tower sheild to there back and battle that way, getting a benefit from it.  Sure, you might manage to negate a couple lost AC points because of it, but you'll be taking a -10 to hit and skill roll!

If they want to argue the sheild makes their back more armored, you could track down the rules for piecemeal armor and let them 'effectively' upgrade their 'back' to something like Plate when they are wearing a steel shield on their back.

If the player is dead set on this, compromise.

Suggest a feat (Shield Strapping?) that allows you to wield a shield when using a 2-handed weapon while taking a penalty to attack (-2?) and accepting the shield's ACP to stack, but only gain half the shield's AC bonus ([AC + Enh] /2).  This will let you emulate back shields, but also certain spear and pike fighting techniques, or even the large sode of samurai armor.

It requires significant buy-in (a feat), but provides real bonuses (Potentially a lot of AC, in the case of hella magic shields), at the cost of a modest drawback (-2 attack, basically allowing any shield to function as a pseudo-Buckler with enough training, but still giving the Buckler the edge in the case of dual wield).

It also, importantly, dodges the negating of an interesting tactical mechanic, namely flanking.  Even if you have a shield on your back, being attacked from opposite sides should net the attacker an advantage of some kind.  And, in the case of a Rogue or other teamwork creature, a big advantage that you should have to play carefully around.
