again - with adequate hardware/RAM, no problem

Concurrent access/usage will dictate if you need more than one server.

no problem - webmail is separate of course, use whichever webmail app 
you like

Timo is working on integrated replication right now, but it does 
currently have proxy capability that I understand works well and makes 
this fairly painless, although I haven't used it...

But I'm not sure if you are talking about 2 REDUNDANT servers (for 
fail-over in the event the primary fails), or 2 active/load-balanced 
servers... proxy would work for load-balancing, and you can configure 
anything to use heartbeat, no?

You'll have to convert to standard maildir:

On latest version (1.1.2 currently), no problem, but a newer/full 
rewrite to provide native sieve capability is in progress, which will 
provide much better control

this is one of dovecots strongest points imo...
