From what I can tell, it is possible in JA, with a rather heavily modified game.
Is it going to happen? Well, I don't think so. It would be a monster task, and pretty much everyone who has the ability to do so is already tied up.
...But dang it would be cool x_x'
It's completely possible with minimal modification to the game, it would just require a client-side mod. Have a look over at Wudan's (creator of the Dragon animation tool) forum:
Um that thread is like soooooooooooooooooooooooooooooooooooo old and I don't see any in game shots leading me to believe it was never completed and never will be.
it probably is old, thouygh il try talking to Eltran creator of stalax, he can probably tell us once and for all if its possible and if someone could do it?
Isn't it possible, to add 2 or 4 bones to the normal human-skeleton? O.o
well it IS possible
but it will be A LOT WORK we would have to recreate all anims in XSi files using the new skeleton and then we will have to re-rig & weight all models in order to get rid of the : model disappearing in cutscene glitch
Making skeletons isn't hard at all, and with XSI's GATOR tool all the animations could be transferred to this new skeleton but then you'd have to re-rig every model to it as well as make all the frames for the added bones. The Q3 engine would need some sort of physics engine incorporated into it somehow to have functioning cloth.
^^^ this.
although, for multiplayer it wouldn't be THAT much work, you'd just need to go over the animations for the MP only stuff with the new bones.
you can simulate physics within xsi/max for the new bones, to make it look realistic, and then bake those down to keyframes. it'd still be a keyframed animation, but it'd look good.
