psyco is a just in time compiler for python which makes python a bit faster. i think you mean the cgkit library? cgkit doesn't support collada or fbx.

it would be great if there were a python wrapper for the fbx sdk somewhere but i didn't find one. i am no fan of c++ but maybe i will look into the c++ fbx sdk.

<edit> hm... i wonder if the ma stands for maya ascii here and if it really is maya ascii how well it works since i guess it's a pretty complicated format. seems to be new. </edit>
