A buffer concept is absolutely essential for TCP. Without it you will
run into delays with Nagle, delayed ack and slow start all combine-ing.

Streambuf makes sense for the iostream concept. For lower layers the
buffer concept needs to be a model of contiguous container. Iterator
type can only be guessed at because I don't know what goes on inside the
'C' socket lib or the kernel but first guess would be forward iterator.
