hierarchical character, copy one animation to another


I’ve got a simple hierarchical character, like a robot. Hip->upperelg->lowerleg->foot etc. type hierarchy of groups and meshes.

In two separate blender files I have different animated sequences for this character. One is a run sequence and one is a jump sequence. I need to combine these two animations into one character. Is it possible?

Right now I’m looking into IPO curves and the NLA Editor, but I’m pretty new to Blender’s animation concepts.

Thanks for any help,
