Google and ZDNet seem to think so. I stumbled on to this Enterprise YouTube coming post on ZDNet in the Googling Google blog by Garett Rogers.

... why would a company want to integrate with YouTube, especially since most are either considering or have already blocked the website from their network? After thinking a while, I came to the conclusion that there are several uses for an enterprise version of YouTube that could make it worthwhile.

Training Videos
Companies are usually responsible for training new hires and even long time employees who are simply moving to new positions. This never ending process takes a lot of man hours that could be better spent in other areas of the organization. It would be easy to create training videos once and upload them to your corporate training application (YouTube) — allowing you to allocate resources more efficiently.

He goes on to cite Corporate Culture and Public Relations as other opportunities for YouTube as an Enterprise App. I wonder about social networking and informal learning as other emerging practices for use of an Enterprise YouTube application. It will be interesting to see what reader comments pop-up on the XDNet site in response-- it obviously has a much wider or more diversereadership than the training and development community and their take on things will be interesting.
