I don't want to have to re-run the tool when new users are added to the
domain and have mailboxes created. I want this to be completely "automatic"
either through group policy or a login script (or a reghack, which I already
know how to incorporate into a GPO.)

Group policy can't write values to individual folders, which is where permission settings reside. If you want to try to write a script that does what PFDavAdmin does, docs start at http://msdn.microsoft.com/exchange/ with discussions in the microsoft.public.exchange.development newsgroup.
You might also want to look at the tools listed at http://www.slipstick.com/exs/permissions.htm
