Another swarming streamer, OPENdj, is also free and GPLed and runs under GNU/Linux. Grandiose prediction for a Sunday: swarming will standardize on a protocol in the next three-five years, abeit one with many implentations.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
