Simultaneous full-screen connections

[Philip Loewen]

Almost all linux setups have a feature I would like vnc to 
emulate: shrewd key combinations (CTL-ALT-Fn) allow the user 
to cycle through 7 different working environments.

I would like to be able to cycle effortlessly between a 
full-screen X session powered by the machine driving the 
monitor and several other full-screen VNC sessions powered 
by different machines around my network. An idea similar to 
what I'm looking for is the 'virtual desktop switcher' that 
many linux users (including me) find almost essential. I 
just want a different machine driving each desktop.

Linux-friendly advice in any flavour would be most welcome: 
the machines we're talking about run assorted distros 
including gentoo, red hat, ubuntu, suse, and more. I want 
full screen access because my poor little thin client can 
only cope with 1024x768: I can't afford to waste space on 
window borders, handles, etc.

Thanks for any suggestions you might have.    - Philip
