Oh, yes, now that you mention that, at Oakton, I also set up the
student and faculty servers so that they do the LDAP lookup for
unknown usernames, and forward the mail appropriately. So, as long as
they have sufficient machine resources, you could use round-robin A
records and expose both machines to the Internet. Yes, half the time
the mail would be in the wrong place, but at least the *other* half of
the time it would, and the mail would never have to transit your slow
link twice.
