I can't remember if this was ruled out further back in the thread, but it's pretty easy to use Aquamacs' emacsclient from the command line, and this is what I habitually do.

% echo $aquamacsbin
/Data/LocalApplications/Aquamacs 2.4/Aquamacs.app/Contents/MacOS/bin
% which aq
aq () {
	if test -z "$1"
	then
		echo "Usage: aq file"
	else
		if ! test -f "$1"
		then
			touch "$1"
		fi
		$aquamacsbin/emacsclient -n "$1" > /dev/null 2>&1 || echo "Starting Aquamacs..." && open -b org.gnu.Aquamacs "$1"
	fi
}
%

Then 'aq foo.txt' opens up the given file in Aquamacs, creating it if necessary.  For this to work, you have to have '(server-start)' in your ~/.emacs/init.el file.

(There's a _very_ similar invocation to do the same thing for Cocoa Emacs.)

All the best,

Norman
