Streams imply connections! There are many applications that can be
adeqately handeled by connectionless datagrams. I reckon there will always
be a need for interfaces supporting both streams and datagrams, and
in this respect Berkeley sockets are superior. Streams are good mainly
for terminal handling (as in V8) but to base your entire networking
on them is surely a bad idea.
