Ask Slashdot: Best way to implement Wave protocol self hosted?

zeigerpuppy writes: It's time to revisit Wave, or is it? I have been looking to implement a Wave installation on my server for private group collaboration. However, all evolutions of Wave seem to be closed-source or experiencing minimal development. I was excited about Kune, but its development looks stalled and despite Rizzoma claiming to be Open-Source, their code is nowhere to be found! Wave-in-a-box looks dead. So Slashdotters, do any of you have a working self-hosted wave implementation?
