[Dovecot] Multiple Dovecot instances over single mail store

I need to run two Dovecot instances with totally different
authentication configs: first - passwordless, based on client SSL
certificate; and second - regular password based (LDAP, passwd etc.).
(As far as I know this cannot be achieved with single Dovecot instance;
if I'm mistaken, please correct me). My intention is to give clients
dual access to their mailboxes: some do own a SSL cert, others do not.
I want to know whether it is possible at all. If possible, how do we
implement proper concurrent access (locking, etc.) between the two
instances to a single maildir-based store? I guess this should be
possible since I know Dovecot can operate NFS-backed mail stores, e.g.
in a load-balancing cluster setup.
Second, is it OK to run the second instance in the same OS (we use
Linux)? or chroot'ed or even virtualized solution will work better?
