Quote - there was a japanese site with BVH files, but they had extra body parts in them. Poser just ignored the extra ones.

Well there are MANY, MANY online source of free BVH files
Some work ,some Horribly distort your poser character
and as a person who has been animating in poser since version3
and has sold BVH/Motion files here and other markets I have Alot of experience with them.
and even the ones that "work" often have your figure way above the or below the poser ground  plan requiring some basic knowledge
of adjusting numerous keyframe over a long range in the poser graph editor.
something most poser user dont have the desire to learn.
and again as a Merchant and  from speaking to other merchants
I can tell you that  pre animated  Motions for poser are a tiny niche market that is barely worth your time
and even then they better be perfect( for V-chick) on delivery as no one wants to have to use secondary programs pyscripts etc to get them working right for their favorite figures.

There is a big thread over at CGtalk about this new KINECT technology and the general consenses(sp?) from the "pros" working
in the animation industry is that people will still need to hand key

Character animation as this is not that holy grail many yearn for not yet .

not to seem like a DAZ fan boi but poser needs  a NON linear motion mixing system  to easily combine/edit /mix premade all those free motions to generate your own custom sequences like 
Like aniMate+
