I've mostly got the code building now, against the current versions of bb-storage.
I still need to test the bb-deployments fork of mine that brings back the event service, before working on improvements.
But EdSchouten mentioned that they would be willing to unarchive the event service as a community project, and cphang99 mentioned they would be interested in helping contribute too.
I'd like to get buildbarn running at $JOB and find a few people willing to help maintain it there too, before I was willing to officially commit to helping keep it alive.
Ed also had some advice for when we start working on actual improvements:
My suggestion would be to not just dump the BES in the CAS and let bb-browser display that
The BES can become far too large for that to be useful
