What's wrong with sockets? They are duplex streams.
You might probably implement them as two separate simplex streams, but
then the concept of *closing* gets unnecessarily complicated.
The analogy with two-way street is also wrong - an optical fiber would
be better, because it is not vulnerable to head-on collisions.

As for the MI, I agree with Dmitry - inheritance should be multiple,
otherwise it is just a special case of something that is fundamentally
more general.
Actually, interfaces are a sloppy escape from real MI. :-)
