btw, shouldn't we, in the general case, create a bridge per user and use 
IP NAT?  If we have a global bridge, users can spoof each other's MAC 
addresses and interfere with their virtual machines.  They can also 
interfere with the real network.

That's not a concern with most one-user-per-machine configurations, but 
the default configuration should be safe.
