Hi Alex,

We have a home brew at work that is a Liveubuntu with some extra mayonnaise. 
PXE-boot (net boot) of the kernel through a boot server (Ubuntu 8.04). All 
runs in memory. Everything you install (from the boot server) on desktop OS 
(Ubuntu) can be saved as a file with apt-get install set and reinstalls 
automatically when you boot next time. This makes us a hardware independent 
up to the point whats in our kenrel. I was not the designer of the system so 
I don't have the intricate details of it but if you're interested I could ask 
(not that hard. the designer is sitting 3 doors down) about them. I do 
remember a caveat about booting. The initrd can't hold more than xx amount of 
data and that made the designer do some trick to get around that. What I can 
about the system is that you'll need at least 2G of memory to run smoothly.
