(it is of very easy for windows to listen for telnet - just bind to port 23.
 The problem is logging in a session. cygwin provides a telnetd BTW
)

However, there's no need to actually log in (telnet, rsh, ssh, etc) to
do any of this.

All you need to do is have a daemon process running, listening for
connections on a port, and spawning off a copy of the program.

inetd would do it on unix (or windows with cygwin). But you can just
as easily leave a console window running on a windows desktop with a
listener.


netcat is good for this sort of plumbing. (I use my own perl
implementation, but the standard c one is similar).


Eg in a cygwin shell on my windows machine: 

$ perl netcat 12345 gnugo --mode gtp

which waits for an incoming connection on port 12345, then when it
gets a connection, binds the socket to stdin/stdout and execs gnugo.
(I think standard netcat uses -e to give the program to exec)


Then on my solaris box :

$ echo help | netcat server:12345

connects me to that port, sends a line 'help' and gets back gnugo's output.

(I can also use telnet client to connect to port 12345 on that machine.)
