Thank you for the comment onpon4!
MediaGoblin is interesting, and hopefully the server install will become
easier once they get to v.1.0. I would like to use it as a private way to
share photos with family and friends. However, it doesn't seem to me to be a
replacement for youtube, or at least for what I do with youtube, namely:
A video repository that allows me to search for video content that interests
me (for example, conferences) and stream them on my browser. I would be
willing to pay for such a service if I could be assured my searching and
watching habits are not being mined.
Gnu has a video repository but it is very very limited.
Cheers.
