I am using SRV records, RealTime SIP peers and 302 redirects (Transfer) 
and a bit of logic in the dial plans to scale our * cluster.  Phones may 
register against any * server and an inbound call will always find which 
server they are currently registered against.  It seems to work well for 
us.  I am still testing the IMAP voicemail backend, but MWI seems to 
work just fine with this setup... the * server the client was last 
registered against handles MWI normally.  Sorry, I don't use DUNDi but 
I'm sure an IMAP backend for your VM wouldn't have any impact on MWI.  I 
am still in a testing phase though, so my experience with IMAP/MWI is 
limited.

btw. How can a phone register to multiple boxes at the same time?  Do 
you mean you could have multiple registrations that have not yet 
expired?  We only ever care about the latest registration in our setup 
and ignore old/stale registrations...
