This means that there's no (easy) way to compile the murder master to
keep its config and meta-data files in a different directory from the one
used by the back-end cyrus IMAP daemon, I guess. Am I right?
No. You only have to add -C option
Hi,
The tricky part is - there should be a master, and it should
probably either be chosen by some sort of election between the active
servers (here lies high-availability heartbeat magic) or by IP address
allocation. Anybody know if avahi and friends can help here?

Dear Andrew,
In a traditional Cyrus Murder (not a unified Murder), there are
3 roles:
1. backends - these store email
2. frontends - these proxy incoming connections to the correct backend
3. mupdate master - maintains the list of mailboxes in the Murder
There can only be 1 mupdate

No. Mostly it's a format difference
Yes, this. Absolutely. The replication code is pretty safe for multi-master
in my branch already. At least for mailboxes. Sieve, Seen and Subs are
somewhat trickier. I think the only really safe way is to keep deletion
entries around and replicate those too so you can tell the difference

Hello,
The cyrus murder/aggregator finds its machines by their names, not ip. You have
to have dns records or all /etc/hosts configured.
You may use virtual machines for the mupdate master, for example, at your
servers.

We have a webmail running on our murder (2.2.x) server, and it uses
localhost as imap server, so it acts as a frontend.
