SysmoBTS?

I've noticed in the osmo-bts project a lot of references to this 'sysmobts' product and I'm /really/ curious. Now, I know that not a lot will probably be able to be discussed for a bit of time, but for those involved, what can we know /right now/ about it? Any ideal target price? Availability? What it can handle? What it can do? I've also wondered how the 'experimental' work of using OsmocomBB phones as a BTS was ever going - did that ever work?
