Its still prohibitive if you want to send video through the channel.
I want to be able to have http proxies perform high level routing
using minimal state and FSM graphs.
I don't care much about wasted bytes, provided they don't cause
the header to exceed the first "fast" packet and they are not a
performance problem at low bandwidth they are unlikely to be
a problem with large data sizes where the control/data ratio
is much lower.
There is absolutely no problem with a 1000 TPS server sending static
files using content length. The vast majority of Web files are static
and
this will remain so - few people use dynamic images.
HTTP has a solution to the content length for variable length data
- chunked. When chunked was proposed the problems with MIME
were understood. I would have liked to see MIME adopted and add
a content length but that was politically incorrect and chunked is
better.
I don't see what the problem is, Web->Mail gateways have to perform
some relatively simple transformations. Big deal.

Not true for real time streams which can become introspective. Imagine
you have a network monitor that is pushing a record of network packets
onto a central display. The monitors own packets appear here from time
to time causing the marker to appear.
The probablistic argument is BOGUS and WRONG. The
probability is not infintessimal, it is real and most likely to bite
people
like us.
But since it is never necessary to use MIME with HTTP the problem
does not appear.
