[Keen to do the same thing.]  I guess those two Dovecot instances 
could run either on (a) the same machine, or (b) different machines - 
though using a network-visible mail storage location.

Does this dual-Dovecot solution become problematic if the mail storage 
location is NFS?  I'm aware of the cautions regarding NFS access from 
two different machines (case (b), here).  If these two Dovecot 
instances were on the same machine (case (a)) but which nevertheless 
used an NFS mail storage location, would we then also hit the NFS 
dual-access problem from this single machine running the two instances?
