thanks for your answer. I'm not really too familiar with VLANs, but I
did look into this once with vde-switch from virtualsquare.org, and
identical MACs were not supported. I suspect there might be VLAN
switch implementations where uniqueness/routing is determined by
MAC+VLAN bits, but I'm only guessing. I will look into this and
OpenFlow, but it would be nice if someone who is in the know could
lead me in the right direction, before I spend endless hours barking
up the wrong tree.
