As long as I can still use dirvish, I don't mind if there are zillions
of systems out there that copy it.  We lose nothing by it, and people
doing things our way are potentially more helpful than people doing
things other ways.  This might result in new features for OS-X that
will help it interoperate with rsync, and that would help us back up
Macs onto Linux servers, for example.

Potentially more troublesome is that Apple might patent their extensions,
and preclude us from using them.  That would be a rip-off;  an opportunity
would be taken from us.  However, if Apple actually copied from dirvish
(ideas if not actual Perl code) I expect they will care more about their
"good guy" image than about harrassing folks like us.  Apple has been
pretty good about sharing most things (Rendezvous, for example).
