It's been my pleasure to see gnome-shell mature over the last few months. I was in Boston last year when it started on the white boards, very cool stuff.
I have been wanting to experimentally get gnome-shell and Zeitgeist into the hands of 'regular users' for feedback. I built a Fedora Core 12 server, and got gnome-shell running. I then tested it over remote display. Clutter failed in my first test because it doesn't yet support 16 bit color depth. I bumped the thin client up to 24 bit color and tried again. I built a page on Live with my results and it's here
The visuals are not working correctly, but once it's up and running performance seems fine.
I don't have the expertise to fix this type of low level bug in clutter, but if anyone with the knowledge wants to find me on the IRC, I will gladly test patches and ideas.
We aren't the only people running thin clients, and one hates to not have this major feature available for enterprise customers that want to run GNOME 3.
