But firefox, on the mac, cannot be configured to use an arbitrary
program or shell script as the mail client. It wants a full-blown Mac
application, which it can activate and then send an Apple event to.
Or have I misunderstood something?

But I am not talking about KDE. I am talking about Mac OS X and its
native GUI.

Now I have been wasting time digging around in ns-win.el and
term/nsterm.m to try to figure out how all this works, but I am not
familiar with OS X internals nor can I read Objective C, so it all
makes my head spin.

But I can figure out some bits: If I run open -a emacs FILENAME in a
terminal, this apparently results in an event handled by [NXapp run]
and gets transferred into an <ns-open-file-line> event which is
handled by the usual emacs event loop. Similarly, if I use the service
menu in another app to ask emacs to do something, a
<ns-spi-service-call> event results. But run open -a emacs
mailto:foo@HIDDEN, and no such translation happens.
