Can you call LaunchApplication on shiny new Mach-O application
packages?
Or do I have to use LSOpenFSRef to do this?

While we're on the subject of application packages, can you call
PBGetCatInfoSync on them? I know this call is deprecated. I've got a
rather large body of code based around FSSpec and I'm not crazy about
the idea of having to rewrite all of that for FSRefs

Some more data on this subject. Turns out that I can call
PBGetCatInfoSync on a package as long as I append ".app" to the end of
the file name. Same thing with LaunchApplication but there's something
screwy there. I'm not 100% sure but it's looking like the PPC version
of a universal binary is being launched not the x86 (which is what I'm
running on) and that code starts to run and then shuts down right away.

LaunchApplication is a pretty old API (as is PBGetCatInfoSync). Look
into Launch Services.

Launch Services works just fine as long as you have an FSRef.
Fortunately there's a routine to make one from an FSSpec.
