Certainly possible.  I wouldn't want to do that myself, since I like  
to poke around in the mapset folder and wouldn't want it to open  
GRASS instead (it would probably already be open in GRASS).

Another possibility would be to use something like OnMyCommand to  
make a contextual menu item that will try to open a selected folder  
in GRASS.

It's in the source, so when GRASS.app is built the functionality is  
there.  I haven't updated my binaries yet.  I'll do that later this  
weekend.

It's a part of the AppleScript startup wrapper (GRASS.applescript).   
Basic Applescript handlers, though figuring out the order that the  
event handlers are called when launching an application had me stuck  
for a while (so that it had a chance to process the drag-n-drop  
before attempting to start GRASS without it and quitting).

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
