Thanks for the encouragement, I hope it will also work as
advertised ;)

As for the idea with bridging - I understand that an
etherstub is not an interface, but rather a switch or
hub. I wondered if this virtual hub can get connected
to the physical LAN (bridged at the ethernet layer)
using a physical NIC attached to both.

Basically, my main concern was that in one boot-up case
the OS has to create all those virtual and aliased NICs
over "rge0" and in another case over "e1000g0". I want
to minimize or eliminate manual changes in configs when
I boot the OI OS image on hardware or in the VM, thus
I wanted both "rge0" and "e1000g0" (whichever is present)
to map to an "eth0" and set up all the rest above this.
If this works, it would reach my goal.
