You can launch a GUI app by using fork/exec with the "open" command.
That's the easy bit. Killing the app from the daemon is a bit
trickier: the pid you have access to in your daemon is for the "open"
process, not the app, and, alas, "open" returns without waiting for the
app to die.
I think you will have to communicate with the shared workspace
(returned from NSApplication) and find out the
NSApplicationProcessIdentifier so that you can kill it. If there is an
easier way to do this, I'd love to hear it.

The daemon is currently a C program and is not linked with any of the
Carbon/Cocoa frameworks. Are there Unix calls that would fit best for
this situation, or should I look at making the daemon link with the
Foundation framework and use NSTask... or link with Carbon and use
LaunchServices?
The daemon will need to be able to kill the GUI app at certain times
as well if that makes any difference.
