As the guy who originally posted this idea, I have some comments (sorry
if this has all been said before but I seem to have missed out on a lot
of intervening discussion).

1) Objections based on breaking network protocols are valid but
not insuperable. Decent self-respecting protocols (e.g. IP) can pass true 8-bit
data transparently, using character-stuffing if necessary. If UUCP can't,
that's a good reason not to use UUCP (though I'm using it now :-)

2) Objections based on breaking cursor-addressing programs like 'vi'
are both valid and serious. I can see no way round this short of putting
cursor-addressing knowledge in the kernel (yech!) or doing the
cursor-addressing through a special process. Window systems essentially
do this anyway, but I don't like having even more setuid processes around,
not to mention the overhead for every dumb terminal.
