Well, you're close -- too close.

It turns out that the vRefNum for looking at the volume contents and the
vRefNum for launching are *different*. Unfortunately, there's no easy way
to get from one to the other.

Oh, and converting the path to an FSSpec (using system calls) returns the
*old* vRefNum, which works correctly for a call to FSpGetFInfo (to determine
whether the file is an application or not), but not for LaunchApplication.

Sounds like a bug to me...
