My inclination is to integrate it into the almost complete
org-mac-protocol. It seems to be working robustly on my system, but
could use some better error handling at the AppleScript level in case
things do go wrong.

That way there is one consistent method of sending data to orgmode from
OS X applications.

Christopher, could I ask you to verify this code and work together

with Alexander on integrating it (if Alexander agrees, of course).

I'll take a closer look in the next couple of days.

Best, Christopher
