TCP vs. UDP changes little (when point to point). You still have packet
even when sent over TCP stream. It is difficult to outline a universal
solution for all case.

There are a reader and a writer tasks encapsulated into I/O objects. There
are packages implementing protocol layers. Each layer object derives from
or otherwise uses the lower level object in a mix-in. Lower layers provide
operations for the higher levels and define abstract operations or callback
to override. Two tasks have the advantage of having it full-duplex
(performance, deadlock prevention upon protocol errors), being able to use
blocking calls. It may impose some difficulties as you would likely have to
route actions from the writer to the reader task.
