1. To get more people interested in testing the upcoming software release.
2. Create a framework that allow many testers using the same system.
3. Create a automation framework then automation.
4. Have some fun << I am serious about this one.

Do you have any ideas on how to achieve any of the above?
Do you have some free time?
Do you know of any relatively cheap hosting for a test bed setup? (You wouldn't need to configure anything; just hop on the machine test, create test cases, or conquer the world.)
