One thing that we have not gone for in Freespace 2 is to animate POF files like that of the Descent Series. With this feature, MODders would have infinite possiblities with POF models. (Although this will change after this has been accomplished.)
The Descent 1 POF Animation Header is given below:
struct
{
int16 numFrames; //Number of different animation states
anim_angs[numframes][numModels]; //The list of anim angles for all models. numModels is number of models (see OHDR block).
}
The code for Descent 1 is available, so check it out and continue to improve Freespace!
