The most straightforward way to do this is to redirect stdin/stdout to
a socket, a pty or a pair of pipes before the program is run, and have
a program at the other end.
For programs which expect stdin/stdout to be a terminal device, you
need to use a pty. Look at the source code for the `script' program
for details.
