I am certainly looking forward to the answer to this question. My %0.02 contribution: When brcmsmac (or its predecessor) first appeared, b43 supported none of the newest Broadcom hardware. Since then, Rafał has done a super job of extending b43, and as he pointed out, the community driver is arguably better than the one contributed by Broadcom. I would like to see the Broadcom engineers concentrate on two things: (1) adding their new devices to b43, and (2) try to get their lawyers to allow the community to redistribute their firmware. It would also be nice if they opened the wl source. I cannot imagine many secrets contained within. Those changes would overcome a lot of the bad will that has been built up in the community. There are many users that reject a particular model of computer merely because it has a Broadcom device included. Larry
