How to Animate Face and Body Simultaneously

[AGP]

I have a one-part model of a human. His idle animation loops constantly. When you talk, he is going to repeat what you say, hopefully without interrupting the idle animation. I guess my two questions are: is it at all possible on jPCT with a one-part model and do the OgreMax exporter and jMe importer (and, for that matter, Raft's Bones's animation) support this?

By the way, I didn't use the Bones board because it doesn't necessarily have to be a Bones question. Although now that I think about it it probably should be, so if Egon doesn't mind, I will re-post it there.
