That's a good idea (especially for something like a 'datacenter' mode
discussed elsewhere). On the other hand we still have a problem of users
disconnecting and reconnecting, eg. someone leaves a machine in
Petitboot, someone else connects and the screen is blank.
I suspect V2 will be a combination of both ideas :)
