Chayzer, just to jump in here I'll add my two cents for a request for more detailed information about the pulseaudio multisync setup, as I've been looking for a long time for software that will actually do synchronized audio playback accross multiple machines (the typical answer is "You can't, too many variables with buffer times/hardware/etc, just get a multi-zone amp..." so I'm very interested).
If you're running the VNC server on Ubuntu it's relatively easy: every VNC instance can run at it's own resolution/color depth/etc, you just have to set it up on your VNC configuration (you can actually have say 3 servers, all running at different resolutions, with a few simple settings). I'm not sure exactly where the setup is for Ubuntu, but on my Fedora box it's /etc/sysconfig/vncservers, and all I have in there is this:
VNCSERVERS="1:rob"
VNCSERVERARGS[1]="-geometry 1024x768 -depth 16"

The standard X desktop is a lot higher than 1024x768, but I found that was a good res to run VNC at so that it didn't consume too much space on my regular machine when VNC'ing in. There are lots of good resources about VNC config available online, just google for 'em.

Thanks!
