xephyr or just remote X?

I want to set up a firefox profile just once, and run it on the vm
directly.  Can be done either using xephyr, or just killing and
restarting when pulling in from a different host.

Let's try the simplest one first.

EDIT: remote X works well.  Just kill existing session before starting
a new one.
