Can you give us so more details? For example: What will the app do?
Your description is very strange, lol.
But indeed, you should create a normal cocoa app that do the stuff
you want to do (UI + the real stuff),
and a little daemon that checks every X minutes if the other app is
running:
yes: ok, continue
no: start app (log message? App was stopped)
Look at CFNotification and the distributed notification center (I
thought there was a Cocoa variant of that, but I can't seem to find
it) for a way to detect whether your app has hung. You could just do a
ping/pong set of question/reply notifications that your daemon sends
to your app and gets a reply. If the app is still running but there's
no reply within a sensible timeframe, something has gone wrong.
