computer-go: Protocols for Go program communication

[Peter.Smith@xxxxxxxxxxxxxxxx]

How do programs playing on the Computer Go Ladder communicate?  Is that
mainly done by people manually typing the moves into IGS client programs?

Is it possible and useful to think of writing interface code which would map
between Go Modem Protocol and IGS / NNGS?

Lastly (I'm pretty sure the answer is no to this) is there any convention
for one program using GMP to say to the other side stop game over let's have
a coffee break and count up instead of saying let's have a new game?
