I remember reading about gauntlets that had an effect what somewhat like Monkey Grip (Complete Warrior feat). The thing was that the wording was off just a bit. How I read it, and my DM agreed, was that you could use this with the Monkey Grip feat, and you player would be able to wield a weapon as though it was two sizes larger.
I think it was in the Magic Item Compendium. What are the gauntlets called? I loved them, but now I cannot find them.
