IMHO the best, fastest, easiest, and most universally viewable way to post a video online is via vid.ly:  http://www.vid.ly

And vatusa would be able to reserve a vanity url for free so that all the videos could be hosted at vid.ly/vatusa.

If you aren't familiar with vid.ly, check out the video on the front page.  It is a pretty cool service, and in my experience blazing fast.
