Keith, >> IP over foo is not exactly packet science, that's why. KM> nor is it standards-track material. Besides the fact that you happen not to like the idea of IP over Mime, what reason is there to prevent standards-track. We make IP-over-Foo specifications standards track all the time. We do not make a point of forcing them to Experimental. So unless there is a compelling technical reason -- especially one having to do with risk to implementations or the Internet -- then what is the justification for withholding standards track status (as long as the specifications is clear and complete)? d/ -- Dave Crocker <mailto:dcrocker@brandenburg.com> Brandenburg InternetWorking <http://www.brandenburg.com> Sunnyvale, CA USA <tel:+1.408.246.8253>, <fax:+1.866.358.5301>
