The only solid one I know of is GOODS
(http://www.garret.ru/~knizhnik/goods.html).  I think Jason Voegele
was working on a Ruby client for it at one point, but I haven't heard
anything from him for a while.  I have a Smalltalk client that
shouldn't be too hard to port, either - at the least, it should act as
a more precise specification than the protocol's documentation does...
;-).
