Yes, you can add other domains to the same lan:

        domU2# modprobe ohlan address=0x1b6000

Currently limited to 32 partitions for no particularly good reason.
Note that like a real LAN, one badly behaved partition can block
communication for the others they share the lan with...

Sorry for the confusion!
Rusty.
