"So, it's not dead but there's (currently) noone working on it besides me and my time for it is very limited (to barely more than zero over the last year). I'm hopeful that I'll be able to find more time, hopefully around summer. That said, if anyone is interested in working on it, I'm more than happy to have the help. I do promise to make some time to work with potential contributors, but as you can see my latency can be pretty bad at times. "
