Yet Another Unarmed Attack Thread

So I've read some of the threads on this but I'm still hurting me head trying to grasp what should be a simple concept (which leads me to believe I'm over-thinking it). In the Ultimate Equipment guide, it states:

Like a normal gauntlet, a locked gauntlet lets you deal lethal damage rather than nonlethal damage with an unarmed strike.

However, based on what I have read in other thread, the strike itself is no longer considered "unarmed" when a gauntlet is used. Is this correct?

If so, is there any classless way other than the Amulet of Mighty fists to add an enhancement bonus to unarmed strikes?

Yes, a gauntlet is considered a weapon, not an unarmed strike.

There's the new Body Wrap of Mighty Strikes also adds an enhancement to a certain number of unarmed strikes a round based on the owner's BAB. Mostly useful for Unarmed Fighters, although it takes up the Body slot that Monk's Robes use.

You can also have Magic Fang or Greater Magic fang cast upon yourself to add an enhancement bonus, too.

Those are the only real options for unarmed enhancement bonuses.
