The owncloud client is using inotify to listen for local file changes.
It can not be used to listen for remote file changes. And it uses the
csync library which performs two way file sync just like unison.

So yes, owncloud already behaves as these solutions you have read
about. The only problem is how does the client determine when a file
changes on the server. That is where polling occurs. "Unison and
inotify" does not address this problem because these are things
initiated from the client to the server. You would need an additional
technology to initiate commands from the server to the client, if you
want to remove polling altogether.
