Cal3D (filetype) animation for use with Vizard

Hello. First post here. Not sure if this should go under Animation or Other Programs.

I am trying to make multiple animation sequences using Blender for use with a python VR program called Vizard made by WorldViz. Their library supports the Cal3D file format for 3d avatars. I am using Blender 2.45 since that is the last one I see that naively supports this file type.

How do I make multiple animation sequences like this? Its fine if blender can’t handle this, just point me to a program that can (preferably at least shareware). I have already made my low poly model and rigged it.
