Interesting but would it not be better to keep all the network stuff in
user space given that most sane environments will have crypto on them ?

It's also a less than ideal protocol in that it can't represent some of
the things termios can, nor can it report arbitary speeds properly.

Is there a reason it couldn't use pty/tty pairs either as is or tweaked
to better report termios changes and allow modem line reporting ?
