Indeed, and I talked to most of the Unity team here in Orlando and they
promised to fix any issue that we see on thin clients. We should just
make sure to test it early in the cycle to leave them time to fix it.

As the new Unity uses compiz instead of mutter and compiz works fine on
thin clients with supported network cards. So my guess is that for
recent Intel/ATI based thin clients, we'll probably be able to run
Unity, for the rest, we'll get a good old gnome desktop.

In real deployments, my guess is that you'll either have Unity working
everywhere and use it or force everyone to the old interface. Switching
should be as easy as a gconf key or a XDG desktop session.

We won't need to do any work to get multitouch working. As the actual
hardware support is built-in X, all events will be sent to the X clients
including utouch. So if you have hardware with multi-touch capability
(new Asus EEEtop maybe support it ?) they should work fine.

So all in all, I'm not overly worried about the switch to Unity by
default as long as we make sure to test it early on and make sure the
relevant blacklists are updated for hardware that won't work (I'm
thinking of VIA based and ION based thin clients mostly).
