Looking for an ediff window setup function - two files in new frames

[fredf . bobdsun]

Does anybody have or know the whereabouts of an elisp
ediff-window-setup-function which makes two new
frames to display the files being diff'd?  It should then
delete the frames when the ediff completes/quits.

This seems like it'd be highly desirable and is probably
already written somewhere.  I want this because I'm
driving the ediff from gnuclient and using an existing
version of emacs.

Thanks,
  Bob
