My mac is running TSSnet Ver 2.0 and it reassigns the node address to 
the ethernet card - becoming the typical aa:... :node:area type. I am 
not aware of and I don't think it is permitted in the Ethernet spec 
to have more than one machine with the same enet address. Its something
else with gateways. At the days where it was still kinetics Fast Path 4, 
we had one on testing which was permitting decnet tunneling on local talk. 
This box had one address, and the macs on the *local talk* cable could share 
it. This is something completely else than the ethernet, and local talk 
protocols take the part of addressing - its encapsulated. 

The LANworks might work differently. We ordered it long ago and are still 
waiting for delivery...
