Please tell me you meant to include a smiley face here?!?
How do you plan on dealing with arbitrary binary data with status
information intermixed? Take a simple GIF file. How would you
recognize the escape codes intermixed with the binary data? I
presume you are envisioning some crazy magic number scheme but this
simply is impractical...
The telnet example just is not at all relavant as to how the
Web should work. It doesn't work that well in the first place and
is not at all extensible...

In _any arbitrary_ data stream. Why bother?
Other than the implementation work involved, what are
the problems that people see with the UDP scheme that Tony and I
were suggesting?
