In my experience a project like this needs to *FOCUS* in something and not just offering GNOME3 and KVM, you should give something special or you won't succeed
You are right a project like this needs focus,
For now our goal is to get a working desktop with gnome3
After that we want to make sure we have easy to install packages of applications (the vanillux-desktop being the main one with gnome3, chromium, VLC and not much else)(for example we will also have the office suite package (optional but offered on install), the lamp stack...
And now come KVM (i really should have explained myself better im sorry), We intend to have one desktop virtualisation package, easy like virtualbox but base on KVM), this is all i meant.
