Python is a lot like java, as far as I can tell. It's kind of the defacto language for Linux scripting as I understand it. What is Poser Pro? I haven't heard of it. FYI, you might look at a product called Blender, which is a free higher end 3-D system scriptable with Python. It's out of the Netherlands but I think there's a link to it in the free software section of 3D cafe.
