testing in the cloud?

[srepmub]

hi all,

I'm waiting for the shedskin tests to finish many times a day.. this
takes about 10 minutes each time, on my quad core PC. so I was
wondering if I could run these completely in parallel instead, by
using some kind of cloud. does anyone have any suggestions/
recommendations for this..? of course the more open/open source based
the better.

thanks,
mark.
