I mostly like it myself.  The major downside I see is that it will
upset people running MTAs on dynamic dialups.  By this point, though, I
think that may be an acceptable price for shutting off the flow from
the open proxies and random 0wn3d desktop boxen.

Another big positive side effect I see is that it will finally give
people a real incentive to do something about all the totally broken
rDNS out there.
