Synchronize two separate owncloud instances?

I would like to have two instances of owncloud on two different servers.
Is there any plugin or tool to do that, existing or future development?



I would imagine it is possible but with much work.

By synchronize do you mean just the files or also the metadata?

Files only would be sufficient.

Local user management or LDAP or Active Directory?

LDAP is what we are using.

Okay, after some research - I can not find a solution for this case, at least not with the current description.

The problem would be the latency to keep everything synchronized.
Also it would depend on the size of your DB / Storage.
