And that works very nicely for things that transport text. It's easy
to implement, easy to debug, easy to test. But, when you need to
transport binary data, it gets ugly and compatibility problems start
to arise pretty quickly.
One could also borrow standards from the old-school serial world and
us the SYN/STX/ETX framing with byte stuffing used by HDLC et al.
