IceBear said:3) It's odd that if you have a dagger and someone draws an AoO from you, you could try to Trip them, but if you were unarmed you can't, even though in both cases you are making an unarmed attack.
That is excatly what what Skip feels you can't and neither do I.
WARNING NOT RULES COMING HERE, SPECULATIVE ONLY
I should explain what I think the Sage says here.
1) A Trip is a unarmed attack.
2) You cannot make an unarmed attack as an AoO.
3) You can make unarmed attacks as AoOs if you are considered armed with your unarmed attack.
4) You can make Trip as an AoO if you are considered armed or have a trip weapon.
