When did you last check the self-hosting documentation? I just poked my head into it and there's a big post talking about why they'd rather people wait on self-hosting.
That said if you liked Fluxer but are not satisfied with it right now (which is completely understandable. It's in beta, after all, not a finished product), I'd say check back in 2-3 months. I would bet that the self-hosting is ready to go by then, judging by the rate of how other things have been updating.
