As far as Keyclone, I don't know if you can "easily" set it up to work for BGs in the same way Ebony set up her ISBoxer config, but there's nothing difficult about manual IWT.

Also, Keyclone does have mouse broadcasting, it's just not very usable. But people don't use mouse broadcasting for BGs because it requires all facing and viewpoints to be the same, otherwise they scatter just as badly, if not worse than they would if you just straight-broadcast movement keys.
