Thank you. Actually since I posted my final script, 
I have really stessed the beast. I had four clients
imaging simultaneously yestereday, that's one
Zeroconf client and one "home" client on each interface.
I also tested ZeroConf address re-negotiation by
creating an artifical address conflict on the other
side of the bridge. Perfect, not a glitch. Samba
performed flawlessly and there was no observable
performance degradation compared to the single-homed,
non-briding scenario.

I am agreeable to this proposal. I think if you look back over
this thread, the background and path to a solution are fairly
self-evident...all the info is there. It's just a matter of
removing some of the incorrect observations (on my part) and
tidying it up a bit. If you were prepared to kick of the HOW-TO,
leaving me with a template and posting instructions, I will do
the rest and perhaps you can then review the result and suggest
any changes.

Because it is, to say the least, a non-mainstream application,
my Imaging Server "project" has exposed me to many interesting
(often frustrating) challenges along the way, including an
innocuous e1000 bug and possible Linux/Samba stack reslience
issues. This particular one is the absolute icing on the cake.
I have left behind in my wake many useful threads on a number
of forums and I intend to bring all these together at some point
in a single Imaging Server HOW-TO document.

Many thanks for the kind words and, yes, I have been slightly
mocked along the way by network purists on this topic, but that
is my own fault really. In hindsight, I feel embarrassed that
I even considered arp-filter and bonding solutions when this
is such a perfect case for bridging...sometimes, when you are
down in the trenches, it is hard to see the wood for the trees!
As a late convert, I must say that this experience has brought
home the supreme advantages of GNU/Linux/Open Source/Community.
Things are much more within your control and there is great
help out there when you need it.
