Cyrus Murder or IMAP proxy.

[UnlimitedMail.net - Carles Xavier Munyoz Baldó]

Hello,
I'm thinking about to use the Cyrus Murder in order to setup an e-mail IMAP 
cluster system. The problem is that I have seen this note on the 
install-murder text file:

[...]
    Note that Cyrus Murder is still relatively young in the grand scheme of
    things, and if you choose to deploy you are doing so at your own risk.
    Many of the failure modes can be difficult to track without a detailed
    understanding of the mupdate protocol and IMAP in general, and thus
    even considering a deployment is not for the faint at heart.

    Sites which think they need the Murder functionality but do not need a
    uniform namespace (no shared mailboxes) should consider other IMAP
    proxy solutions.

    At the same time, we are using it successfully in production at
    Carnegie Mellon.
[...]

Then, for a production system, should I use an IMAP proxy solution instead of 
Cyrus Murder?
Is there anyone using Cyrus Murder in a hevay loaded production e-mail system?

May you recomend me an IMAP proxy?
What I'm losing if I use an IMAP proxy instead of Cyrus Murder?

Thank you very much for your help and time.
