Most OSs allow you to do IP aliases on the loopback just as you'd do  
for any IP interface.  However, selecting which one for which cell is  
just as much a pain in the tukkus as selecting an alternate port #  
for the fssync communication.

I'd say the best bet for someone really needing to run multiple cells  
off of the same server would be to use some virtualisation  
technology, such as vmware or Solaris zones.  That'd be my idea...
