Well honestly, I had incorrectly assumed network port space was global, 
when in fact it is private for each IP address(which is why I didn't 
bother to running multiple instances).  Also, AFAIK in the Using Samba 
book(1st ed), 'interfaces' is described as network/netmask pairs. 
That's inconsistent with intrepret_interfaces() comment, but then again 
the book is over 2 years old:)

So thanks, I can now run multiple s/nmbds per IP address which gives the 
   behavior I was looking for with virtual hosts ;)
