preferred VIFS

Hi,

I have a setup where four machines are sharing 12 VIFS. Ideally, I'd like 
to specify three preferred VIFS on each machine - to help with load 
balancing. Can I do that?

I have 12 IP addresses handling IMAP proxy servers, and 16 handling smtp 
and DNS services. It's essential that the IMAP services are reasonably 
distributed, so I've built 12 VIFS with one IMAP address in each.

If I can only specify one VIF per host, then I'd have to load that up with 
all the smtp and dns services to ensure the best load share under normal 
conditions. However, that would mean all my ancilliary services failed onto 
a single host, which isn't so clever. That, or I'd have to think harder 
about my load conditions.
