This restarts crashes processes automagically:

Sadly not, my understanding of KeepAlive is that it controls invocation. That is, it determines whether or not to start the job. My problem is that the shell script being invoked fires up iTeleport, at the end of the launchd task, iTeleport is forced to quit as a child of the shellscript.

If I invoke the shellscript directly iTeleport stays up if I invoke it through launchd, it gets killed. :-/

Why don't you just launch it with nohup then?

nohup /Users/gavin/Tools/iteleport_watcher.sh &

Nope, nohup is trumped by whatever launchd is doing to kill the process. I think I'll go dissect a login item's file.
