BetterAuthorizationSample is your friend.

You might find the following interesting.

Also, BAS has lots of comments and documentation.  And DaveZ's Google 
TechTalk is definitely worth a viewing.

launchd daemon launch-on-demand using Mach ports requires 10.5.  It 
definitely works on 10.5; the system wouldn't boot otherwise.

launchd daemon launch-on-demand using TCP sockets works an advertised 
on 10.4 and later.

launchd daemon launch-on-demand using UNIX sockets works an 
advertised on 10.4 and later, but it's not particularly useful 
without SockPathMode which is available on all platforms starting 
with 10.4.6.
