I promised a mate I'll ask around about a little issue he's having.

Having a website, where user's log in and based on their roles can watch training videos.
Each video pretty large and take a while to buffer. After you watched it, it's ok to watch it again, as it's cached on the local machine.
However when you restart the machines of course those caches are cleared and going to your video's again, you start all over.

Want to figure out something that will work if different users, using different accounts use the same machine, so "save to your computer" is not really a solution.

Any ideas?
