Hi Kirk,

I wanted to thank you for your informative and helpful post. You've straightened out the client-server (or not) aspect for me and thanks for the pointer to the demo and the bit of history about the demo. Its all very interesting and I'm re-energized to try again. I'm still not clear on whether DO can provide notifications but I'll discover that as I go.

All the best,

Steve

I would look at Distributed Objects again. It really isn't intrinsically "client-server" oriented any more than Cocoa is. A client-server architecture is just one way to use the distributed object functionality. It does tend to be easier to have a single- source-for-truth to keep things organized, however, but that is a general data problem not related to DO.

For a possibly useful demo and source-code, check out "Distributed Objects Demo" at <http://www.thotzy.com/THOTZY/Codez.html>, or just go to thotzy.com and click on the "CODES" navigation item at the top of the main page.

The demo implements both same-machine and local-subnet DO, and several different threading schemes.

The demo also demonstrates painless Bonjour using NSPortNameServer without needing to fuss with NSNetService or NSNetServiceBrowser.

The demo was originally written as a bug-report demo to reveal a port leak in certain configurations of threaded DO. That port leak appears to have been fixed in Leopard.
