One major problem here is that a one-character TCP/IP packet is too big
to fit in the TB's reverse-path packets.  If you attended San Diego Usenix
and used the terminal room, its Internet connection was via Trailblazer,
and it worked fine... thanks to Van Jacobson's header-compression code,
which shrinks things down enough.  Unfortunately, I don't think Van's
code is generally available at the moment.
