Sorry about the lack of updates, @Shorigan. It's taking a little longer than we expected to get the beta on JIRA server rolling, but we are getting closer to a release there.
We should be rolling a beta of the Confluence Server version of the plugin soon. If you'd like, I'd be more than happy to add you and your team to the beta tester's list. Just let me know.
While I don't have a firm timetable, we are definitely a lot closer than we were in February.
