Definitely educate me, but: what is Vimeo doing for a B2B solution that Youtube can't provide? You can provide unlisted videos (and that is something a few pareon users have done).
It's odd because Vimeo was most known to me for hosting art portfolios, so seeing it denounce it's "indie" status is bewildering. I assume the advantage comes from providing uncompressed videos with extremely high bitrate. Which is an admittedly extremely niche market.
