Feedback on Hypertext Mail Protocol (a.k.a. Stub Email)

Hi, I just joined this list after being directed to it by readers of 
my recent article on CircleID:

http://www.circleid.com/posts/hypertext_mail_protocol_aka_stub_emaill/

Before publishing this article, I was unaware not only of this list, 
but of IM2000 in general, having been out of the academic loop for 
about 8 years now, and professionally busying myself with writing 
better web applications rather than thinking about bettering the 
Internet in general.

There are over 1600 messages on this list over a period of about 5 
years, so I was wondering if someone could write about 3 sentences to 
fill me in on the current state of IM2000 affairs, as well as what 
primary objections to my idea--or ideas such as mine--may have already 
been aired on this list.

Thanks,

Nathan Cheng
