You don't need to negotiate. If your settings don't fit your opponent's:
there will be no match. If both players configure the same (static)
parameters for their match-request, there can be a game.

[for handicapped games, the negotiation is even more painful, because
the handicap/komi is established *after* the game has started]

No. for several reasons:
1) there is a lot of functionality for human operators to interfere with
the bridge or the go-playing-program (via talk/tell or
"channel"-shouts), which _could_ be used for cheating.
2) it is not (yet) stable / fully functional.
3) I'm not sure yet if I _want_ to share it. I'll think about it.

It is no rocket science, though. just some basic socket/select/pipe/exec
stuff. Most of the code deals with parsing NNGS's replies, filtering out
the shouts-noise, and matching them to our requests. Could be done in
perl, probably, if you are able to avoid blocking on read().

No. Currently there are only ratings for 19*19. (Ladders for both 19 and 9)
Could be changed or added, if someone is willing to look into it.
Rating is based on pem's mlrate package.
[ NB the ladders/ratingcode has not been tested/verified for several
years, some of it may be be broken. Since it has not been altered, this
should not be a big problem, IMO]
