Desktop sharing with Compiz enabled. Currently you can share an Ubuntu desktop (System->Preferences->Remote Desktop) easily, but viewing these shared desktops doesn't work with any of the regular VNC clients (vinagre, xtightvncviewer, etc) if Compiz is enabled...which on most Ubuntu desktops is true by default. This leads to a confusing experience for the non-technical user.

I've recently switched over from using the built in VNC server to just exporting the display through ssh (using the -X option), since I'm usually tunneling VNC over ssh anyway. This obviously doesn't help when you actually need to control the desktop, but I found that I usually just wanted to use specific programs remotely, so it works for me.
