	Consider this use case: I travel a lot, and stay in hotels
 with network connections. Unfortunately, these  nigtly billed domains
 have very poor mail gateways; I've been burned before. I now connect
 directly and deliver mail from the MTA on my laptop.

	I do not know, a priori, what the IP address is likely to be,
 and getting DNS changed for datasync.com would take days, not hours,
 by which time I would no longer be at the IP.

	I do not have co-located servers; and my normal machine may
 not be accessible from outside to tunnel to. Just like the postcards
 I mail from the Hotel, the return address on my email points to a
 valid mbox. 

	Would there be any way to implement tihs use case with
 everyone using SPF, and telling spamassassin to deep six failures?

Okay, Okay -- I admit it.  You didn't change that program that worked
just a little while ago; I inserted some random characters into the
executable.  Please forgive me.  You can recover the file by typing in
the code over again, since I also removed the source.
