Productive uses for an idle web server?

I have been renting a Windows 2008-based Virtual Server from 1&1 for the past few years. It is located in a well-connected server farm, has 10 gigs of space, and unlimited Traffic. I used to host my Subversion repos on it, but have started doing this locally; therefore, I have no use for the server any more.

However, the contract runs until January 2011.

What is a productive (and legal, and useful) use the server could be put to until the lease expires? I was thinking of something like the SETI@Home project, but I'm not aware of anything similar in the web field. The server's not that big in processing power, but as said has good connectivity.

Any ideas?

Solution 1:

You could run a long running torrent server for free software projects like ubuntu, centos, etc etc, basically allowing quite a few people to benefit from this bandwidth. Should also be completely legal. Maintenance would also be very low.

If you wanted to be more involved you could do full mirroring / hosting.

Solution 2:

Look into tor (The Onion Router). If you have a fair amount of bandwidth, and specially if you have unlimited traffic, your server could be a valuable addtition to the tor network. Have a look for yourself and see if it sounds useful: http://www.torproject.org/
