some people have asked me why I would want vimage..
The answer is because it allows you to do lots of things easily
that are hard to do normally.

I can give a very simple example of something you can do trivially on 

Make three virtual machines on yhour laptop:
The base machine and two others.
Have the first 'other' machine be assigned an IP address on
your HOME LAN.
have the second virtual machine have an IP adddress on
your WORK LAN.
use the base machine to run encrypted tunnels from where-ever
you happen to be to your work and home.. when you put the laptop to 
sleep (assuming the tcp sessions are quiescent (no keepalives))
then when you wake it up say an hour later.. as soon as the base 
machine has an IP address.. viola, your session on the virtual
machines are still alive.

there are SO MANY things you can do with this..  and the framework
allows us to proceed with more virtualisation including
separate PID spaces or processor quotas etc.

BUT the framework will never get the mindshare needed unless people 
start playing with it.
