With several well-designed protocols ambient to handle this particular
application anyone who jams HTTP around the problem, I really might enjoy
imagining fates worse than simple predictable failure. Put another way,
there are a thousand ports in the net and each should offer visitors the
best from their particular domain. Those who wish to turn HTTP into
container for all that litters the landscape wish for a sack of trash.

I can imagine some useful circumstance that might loopback a MIME boundary
marker in a streaming HTTP connection but making the second loopback
without understanding and provisioning a filter, with a capability to
escape the marker, would be commiting a serious design error, likely with 
other unintended losing consequence.

And I'd thought with all those fine modern physicists working there that
Oxford would have finally left 19th C. methods of modelling the universe
behind. As Ned Freed and Jeff Mogul generously explained, unintentionally
spitting out any very large random number is significantly smaller than
other more harmful sources of noise in the system.
