Re: Video Page?
Well, if they all upload their videos to your webserver, you’ll have the urls and additional data like title, length, viewed,… in your database. then you just need to grab that information, display it nicely on a page, plug the url into a flash player, paginate everything, sort it by upload date and you’ve got yourself a video wall. You could take a look at WordTube. I used that on a nomal WP install to make something like a videowall. Not sure if it works with WPMU, but you could modify it.
Or you could use YouTube and use their API to enable uploading to YouTube from within your site. Your users would still need an account, though…
