Update: So I just discovered that the installation of Ulteo wiped out my Apache default vhost config in sites-enabled.. which was serving other stuff on my machine. Be very, very careful, as I don't see this in the documentation anywhere...

I've installed Ulteo Open Virtual Desktop on my home Debian server to check it out.. I read about Ulteo quite some time ago, when Gaël Duval announced the project after being sacked by Mandriva. Essentially it is a virtualisation solution, but differs from others in that the virtualised desktop runs inside a browser window.
