I gather then that to cluster cyrus, you need to not only share the actual mailboxes but also /var/imap?
No.
http://asg.web.cmu.edu/cyrus/ag.html is a very interesting read on clustering cyrus servers.
This solution does not appear to support HA. If one backend server goes down, all its mailboxes go with it.
a courier-imap/dovecot box would only just have to access a SAN and that is all there is to clustering. Multiple courier-imap/dovecot boxes hitting a database for user info and mailbox location and then hitting the san for the files. simple.
