Really? You seemed to refer all the time to the container having to do
anything to get this to work, to "client proxies" having this
versioning, and all that. Which is not right.

The client gets a snapshot of the data, INCLUDING a version number.
Client then edits that data. The the client sends back the data. If the
version on the server is the same as in the snapshot the client is
sending back, then all is well. If there is a mismatch then some other
client made an update, and the client gets an exception.
