"This free download contains all the software you need to setup a project similar to seti@home. The client and server were written in java and will allow you to enjoy a diversified cross-platform user base. Distributed computing works under the premise that 80% of a user's cpu time is unused. By installing this light weight client on their machine you can unobtrusively harvest their spare CPU cycles by running in the background. The best part about this distributed computing model is that it is open source and can be freely modified. This zipped file contains a windows installer for both the client and server, along with a JDBC driver for MySql."
