Well, apparently a settlement has been reached in the lawsuit, and it isn't going to trial. We don't yet know the terms of the settlement, and perhaps never will. Haven't seen any official response or roadmap yet, but am a lot more hopeful we can all get back on track making XF the world beating product it already is!
Anyway, yes, it should work with JomSocial, as AFAIK JomSocial triggers all the appropriate J! plugin hooks from the JUser API, which JFusion sits on to do it's magic.
So ... as soon as I see something official from KD committing to XF's future, I'll get back to work on this.
