Jordan Hubbard Discusses NextBSD at BAFUG

Jordan Hubbard spoke recently at the Bay Area FreeBSD Users Group to discuss NextBSD, a "spork" of FreeBSD. He "covers why mach ports are extremely useful in some cases and no UNIX IPC primitive is an adequate substitute." There's a video of the BAFUG talk and copies of the original slide deck that goes into some detail about NextBSD.
