This is something that we might provide soon :)

It is better to use the ChangesTab for tracking the changes. We already 
have a version of the ChangesTab that works in client-server mode and it 
will probably bundled with the next Protege beta build.

Well, we have a class named ProtegeJob (which has been recently added in 
SVN) which allows the programmer on the client side to run a job on the 
server side. Probably you can use a ProtegeJob to transfer data between 
client and server, but I have never thought about it.
