However, should we be considering a solution that replaces the email 
infrastructure as a long term answer to spam?

Personally I think we should, with the following reasoning:

1. The (modern) spam problem has been around for at least 7 years,
   I have discussion notes with many of the same topics going back
   to at least 1996.

   Since we're still not making much progress I think it'd be a bad
   idea to cut off ideas, de facto, just because they have a longer
   horizon.

2. This is not to say that proposals with a longer horizon should in
   any way preclude ideas with a shorter adoption period. But as I see
   it, given the seven-plus year history, it may be unwise to rely
   only on the possibility that someone is going to come up with a
   quick fix.

3. It's not clear how to measure these claims that certain changes
   would require years and years to adopt.

   Although it might be reasonable to claim that it'd be years before
   a major new mail protocol were adopted universally, how much of the
   net would have to adopt it before it'd make a significant
   difference in spam reduction?

   For example, if the top 10 ISPs were to adopt some sort of
   significant infrastructure change which reduced spam passing
   through or to them wouldn't that likely reduce all spam
   significantly, even if it only represented a .0001% adoption?

   (this of course presumes some sort of continued inter-operability
   with non-adopters.)

4. Just the same, having looked at some of the suggested alternatives
   to SMTP, I'm not sure they're quite what they're claimed to be.

   By and large SMTP is just another little text-based:

          VERB [NOUN]* <CRLF>

   protocol (HELO host.name, MAIL FROM:<x(_at_)yz(_dot_)com>, etc.)

   The proposals I've seen just add some new verbs, possibly with the
   intention of replacing some existing verbs, but otherwise are
   pretty much the same thing.

   SMTP has had verbs added before (EHLO, ETRN, etc.)

   One could even imply a major change in implementation (e.g.,
   extensibility) and not really change the protocol much beyond
   adding some new verbs.
