Certainly looks interesting.

I guess the baselayout-vserver packages is somehow for setting up each
of the guests?

QUESTION: Where does X run? In the host or separate copies in each guest?

For a long time I've wanted to set up a single piece of hardware for
my parents, but with two screens, two keyboards, two mice. Each user
would have what they expect in front of them physically but it's
really a single computer. Can that be done using this software?

Thanks,
