I know of some large cable internet providers that block access to 
"external" SMTP servers by default -- but allow unauthenticated access 
to their SMTP server.  Will this be a problem?

By most significant I mean as measured by quantity and not severity.  In addition to frequent immediate vulernabilities client-side scripting can also operate as an execution point for other additional vulernabilities not directly associated with client-side scripting.  It is my opinion that the only way to solve this security problem is to either break HTTP or eliminate client-side scripting.  I find there is no reason to break HTTP since it is working perfectly well and is not to blame for this problem.  Client-side scripting cannot be removed unless an alternative convention is proposed.

If a solution is not proposed the security flaws of the system will become so significant that the commerical value of financial transactions and PII leaks will eventually result in abandoning the internet as an open platform in favor of more secure proprietary technologies.

The idea is that interactivity from client-side scripting can be replaced by transaction interactivity.  Since mail servers are intermediate agents in the transmission, opposed to an end point like an HTTP server, they can make processing or scripting decisions upon data without that scripting having to exist on a client system.  In other words, it is basically an inverted form of AJAX that does not execute on the client-side.  The idea is easily possible using SMTP, but is not possible over HTTP since HTTP does not have intermediate agents between the client and server.
