You're looking a bit in the wrong place. What you want is an agent that
registers "NoInputNoOutput" as its IO capability. You could e.g.
experiment by using test/simple-agent. Find the two places in it that
say "DisplayYesNo" and change them to "NoInputNoOutput". Then you can
use that script as a "just works" pairing initator or acceptor.
