To be frank, i did not think this because there is some serious problem
in the existing replication mechanism. But the below might be considered
for your question.

* The unchanged attribute is never sent to other server. Always the
  changed attribute is sent instantly.
* The above delta sync does not maintain a changelog, because the
  changes will be sent immediatly as it happens on a server and
  unreachable server receives an offline message. Hence no need of
  a changelog.
* N-Way multi-master + multi-salve combination is acheived. You could
  change the role of a server to master or to slave without the need to
  change the configuration file and restarting the server.
* If its secure environment and if xmpp ports are opened this can be
  used as proxy as well. But I dont know such environment exist.

* I learn openldap and xmpp.
* Its FUN.

Definitely this can't be a default replication method for openldap, but
I am thinking what if I make another directory server to sync to openldap.
