One concern I have with the bpycollada importer is the use of numpy and datetime modules by pycollada which it's based on. Particularly numpy as it's use seems to be for things like matrix transforms and things that are already possible with bpy. Having an extra dependancy to duplicate features just seems wrong to me.. But the alternative is forking pycollada and rewriting a large chunk to use blender specific features.

pycollada also uses pil for some features and that's not available for python 3.. I've not looked closely at how much of a problem that would cause though.
