There's already three client libraries:


Perhaps there is some confusion? The D-Bus server, or "bus", is a
service which allows many-to-many communication between clients. You
do not need an implementation of the server in Haskell to use D-Bus in
Haskell applications, and (to my knowledge) there is no API for the
reference server.
