Anyone got experience with blender and motion capture?

Hi, im a total animator noob, for that reason i have been looking around for the slim chance someone has ever created an armature in blender with all the basic animations a 3d human model would have. I have found tries here and there, but no one has ever completed anything close; but while on my search i stumbled on GPL motion capture libraries that can be imported to blender.

Has someone here ever tried to incorporate them? Do i have any chance to try and fuse the ones i think most useful in a single armature?

I would like to hear someone first experiencies to help me decide if it wont be extremately complex.
