Do this with bash, which lets you open two way connections to a
socket. Something like:

	awk -f myprog 0<> /dev/tcp/host/whatever/the/syntax/is/in/bash 1<>&0

I think that's right... :-)  (The <> opens for read/write.)

This whole discussion is interesting, but I think the wrong approach.
I think it would be done better as a dynamically loadable builtin function
than in trying to stretch the language any further.

My two cents, of course.
