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.
