Fabian,
While your idea is very cool, I think a greater degree of reliability 
and simplicity can be obtained from using a central MTA + LDAP server 
containing a mailhost attribute for each user, with a normal cyrus 
server at each remote location. I did this at our company with Sendmail 
and it's working like a champ, and was very easy to set up (not counting 
the LDAP server which was already running in production).
