It is also very much possible to run two separate instances of Cyrus on
one server, with different imapd.confs and cyrus.confs and spool
directories and configuration directories and what-have-you... sieve
directories, which typically reside within the configuration tree. Look
for the -C option for - well, every cyrus executable :)

I've had a system running multiple Cyrus instances, frontends and
backends, on same physical servers at the same time in production for
half a year now. Works perfectly.

The unified murder works less than perfectly, or at least did in version
2.3.8. For instance, copying messages from a folder in the mailstore you were
connected to a remote folder was impossible, as was copying messages
the other way round. (Copying messages between local folders or between
remote folders did work.)
