dovecot - Jun 2014 - Replication with virtual users and static userdb possible ?

Is it possible to get replication working in a virtual user setup
that uses a static userdb ? My environment is fairly simple and typical
- there's a single system user (vmail) that owns all the home dirs
(/var/mail/domain.com/user). The virtual users
(userid at domain.com:secretpassword) are kept in a single file
(/var/mail/domain.com/PASSWD) that's unique per domain, and referenced
as a static userdb : 

passdb {
 driver = passwd-file
 args scheme=plain username_format=%u /var/mail/%d/PASSWD
} 

userdb {
 driver
= static
 args = uid=vmail gid=vmail home=/var/mail/%d/%n
} 

I know the
wiki http://wiki2.dovecot.org/Replication states that user listing must
be enabled, but that's not available for a static userdb. The wiki
http://wiki2.dovecot.org/UserDatabase/Static also says that it shouldn't
be a problem because it will use do a passdb lookup instead (except for
PAM which isn't used here). 

Unfortunately, it's not working. I've
testing with ssh : 

dsync_remote_cmd = ssh -l vmail %{host} doveadm
dsync-server -u%u -l%{lock_timeout} -n%{namespace}
mail_replica remote:vmail at server2.domain.com 

as well as with straight tcp (SSL for
later) 

mail_replica = tcp:server2.domain.com:999 

/var/log/mail.err
shows the problems ...

Anyone else have it working ? I'm sure it's
something simple that I've just overlooked.

Ugh, stuff got mangled in formatting below. Anyway, I've had no luck 
with
various permutations, so it's looking like a virtual-user setup can't 
make
use of replication ?

I guess what I want is for it to activate replication upon ANY 
notification
of updated emails.

I'm trying to avoid switching the userdb from a nice simple static
setup to something else to enable replication. Is there anyone using
replication with a virtual user configuration ? How did you do it ?
Actually, anyone doing replication at all - what does your config look
like ? 

Thanks -
