Question: Can you run multiple zones off of a single NIC, all sharing
the same MAC address?

Answer: YES.  Set up virtual NICs with different IPs, and give them
all the same MAC address.  Solaris will do the right thing.

Documentation Links: (This is all quoted)

In particular:
contains a section on how to set up a zone.

The zonecfg(1M) man page has more info as well:

as does the zones(5) man page:

Configuration help:
I have some experience with this.

get a list of your zones with

   zoneadm list -vc

get the config for a zone with

   zonecfg -z zonename info

then setup exclusive mode ip if needed.

better yet .. run snoop to verify your MAC address data and you shoudl
see the same MAC for all your traffic from that one NIC

Thanks again everyone!
