B2B video possibilities

I hate it when the B2C media seems to move faster than B2B.
Yet in this article by the Associated Press, it seems that our brothers in the consumer press are well ahead of us in the fast-growing world of downloadable video.
I've written about this subject before, and wondered when someone in B2B would make a move. I still haven't seen anything interesting. And that surprises me. It would seem to me that this new, do-it-yourself TV distribution is perfect for B2B. Industrial training, continuing education, professional certifications --- all these are well suited for downloadable video on demand.
For example, Primedia already operates Interactive Medical Networks, which provides continuing-education courses on DVDs and by Web broadcast. But IMN does not yet offer video-on-demand services.
I'm looking forward to hearing about new VOD offerings from the B2B world soon.
