That's neat - I wonder if there is a hard limit, becuase I suspect it should be able to handle any number of zones, provided he can rig up sufficient virtual interfaces for them - he'll probably run out of IP address space first... I would think that respinse time would suck, as everything would swap in and out of local memory, but if all the zones are inactive (as it seem they are), the delays caused by the swapping may be unconnected to the number of zones running (they are only swapped in/active when an "echo" request is received over the interface).
