I vote that **all** Ubuntu variants be allowed.

I intend to make a list of all of them below, if for no other reason than to see how many there are.

 - [Ubuntu](http://ubuntu.org)
 - [Kubuntu](http://kubuntu.org)
 - [Edubuntu](http://edubuntu.org)
 - [Xubuntu](http://xubuntu.org)
 - [Lubuntu](http://lubuntu.net)

Feel free to add to the list as necessary.
