Introducing Supercell: test infrastructure for any open source project

I'm excited about this project for several reasons. It's a totally open stack (Linux, Ganeti, Django, etc.), funded through a grant from Facebook based on code from Google and OSU OSL (including Google Code-In students). This is a great example of the open source community working together for the greater good.

It's a great idea, but free operating systems running on x86 are in practice the <i>easiest</i> test environments to source.<p>It's environments like solaris-sparc, irix, hpux and aix which are harder to rustle up with limited resources.

How does this compare for most open source groups to the option of using Hudson on their own servers? Also, I looked at their list of planned hosts--I didn't see windows. A number of the open source projects that I release are cross platform. Does anyone have any insight if they plan to add instances of windows (xp, vista, 7) for testing? I guess I'll have to wait and see when it's open for general testers.

Ganeti?
