I just ran another experiment. I created a launchd .plist for my
test server and started it using 'sudo launchctrl load ...'. The
server was running as 'nobody'. My test client could connect, get
the vended object, and execute code in the server.
I then restarted my computer, letting launchd start an instance of
my server at boot time. I again ran my client and it had no problem
connecting with the server.
To be thorough, I should probably repeat this experiment as a
StartupItem in 10.3, but so far I'm not seeing any limitations --
at least not in 10.4 and launchd.
Curious. Are you using Mach messaging?
As someone else noted, you cannot send Mach messages between Mach
namespaces, and the boot namespace is distinct from that of the
logged in user(s). You also get a new namespace if you login via
SSH, I think, so try testing your app that way as well.
My only other thought, not being that familiar with launchd, is that
perhaps your server isn't really being launched in the boot namespace
at all, but your user's? Can you connect to the [same] server from
two different logged in users (i.e. using fast user switching)?
