To begin with: You seem to plan to use ozone in a distributed environment. IMO
ozone should provide distributed features itself without the need to handle to
much of these things in the client code (therefore the answer to most of your
questions is 'no'). ozone is designed with the goal to evolve it to be a
distributed system. However, these things are not yet done. Do you have
experiences in the field of distributed computing?.

Hmmm.. I did not try this yet. You would have to transfer the value of the
objects from one server to the client and back to the second server - not very
efficient, I guess.

No.

OzoneProxy does not provide a public clone() method so far. Anyway, there is no
API to create a client side copy of a database object.

I don't follow. Can you explain a bit further?
