That's exactly where the difficulties come from.  Cyrus is a royal PITA
to convince to run on a machine that also has shells. 

For instance: in my case my local mail provider doesn't support IMAP
(and their mailserver is quite a long way away from me and behind
some rather laggy and slow pipes).  I wanted to be able to run Sylpheed
when I'm on the X console and pine when I'm remotely logged in.  The
only option (given that they use different mail formats) seemed to be to
dump all of my mail into a local IMAP server (it's not a ton of mail
either) so both programs could see it.  While the uw-imap can do this
with a bit of prodding (you have to change a variable in a dependancy 
to get it to no spew your imap directories all throughout your home 
directory), it works OK.  I originally tried Cyrus IMAP (because it
was supposedly better), but nearly pulled my head off trying to get
all of the authentication/permission/configuration/login/etc issues
worked out.  I never actually did successfully create a subdirectory 
on the Cyrus server, and after poring over the tons of not-very-helpful
docs, I eventually gave up and went to the uw solution.  UW might
not be the best technically, but I wasn't going to have to spend 6 
weeks learning the intricacies of the permissions system on my
IMAP server to get it working.
