While I agree just about everything that Mark has to say about NFS (been 
there, done that, got the T-shirt as well), it is probably worth pointing 
out that the Cyrus Murder is just a (very clever) IMAP proxy.

Other, generic, IMAP proxies can be used with the UW server.

Perdition is popular:

Fastmail.fm, probably the largest single IMAP service provider that 
exists, use nginx to front their Cyrus cluster:
