This seems like a great idea!
It got me thinking one step further about having a small preconfigured virtual machine that I could quickly move to any of my computers and continue CPU crunching from where it left off.
As a suggestion, you should really provide some comparison on the site between the 3 distro versions' features and install sizes.
Thanks for the reply!
We already have VirtualBox support planned and you can find the description of it here along with various other projects coming up.
As for your suggestion about the website, I think that enough information is provided through the graphics, small descriptions and names of the OS spins but your idea will be noted for when we decide to rejuvinate the website in the future. Simplism is key to effectiveness here.
