Is there any official or unofficial sample code showing how to trigger a launchd process using Mach Port?

According to TN 2083, it is possible starting with Mac OS X 10.5 to start a daemon with launchd using a Mach Port. (1)

I looked for sample code in the documentation, Technote and Google with no results so far.
Would there be a Darwin daemon using Mach Port to be started?

I think you just use the launchd API just like it's done in SampleD (http://developer.apple.com/samplecode/SampleD/ ).

But instead of retreiving sockets (using LAUNCH_JOBKEY_SOCKETS and launch_data_get_fd()) you retreive your mach port (using LAUNCH_JOBKEY_MACHSERVICES and launch_data_get_machport()).

The way to define a service in your plist is defined in the MachServices section of launchd.plist reference (man launchd.plist).

And in the client application, you retreive it using bootstrap_look_up() (from <servers/bootstrap.h>).
