What is it that you are averse to? A persistent connection? A fixed
handle for your service? It's difficult to suggest a mechanism to
replace DO when you don't say why you don't want to use it...

Ok, well, frankly, the previous versions of these app used Core Data over DO (a situation which I understand was never intended), and the code is a mess and quite fragile. So we decided to take a much simpler approach for this version 2 rewrite, and use the built-in web server as the distribution mechanism.

The two apps that are going to be communicating* will have similar, though not identical life times. In general, my app is going to be launched first, and will be gathering data; the remote app will likely come online later, and then gather all information collected thus far by my app, and then start listening for when my app acquires more data to it can keep up-to-date in more or less real-time; this is so that the remote can always have the latest data, in case my app quits (my user goes to lunch, or is done for the day and leaves the site, for example).

So basically, yes, KISS is our motto (or at least KIASAP), so we are looking to keep them untethered if at all possible. An ideal solution would be NSNotification that works across a LAN.

Does that help?

*In theory, it could be that more than one remote app is going to be interested in retrieving the data that my server app is gathering, but in practice, it's likely going to be just one. Another reason we went with the simpler apache delivery system.
