ok. that sounds fine to me. does anyone have experience with this like 
this? i mean do i have to contact 3com and broadcom and obtain some sort 
of permission for this? how does this work?

linux bluez has rpm that contains firmware. it seems like they have 
contacted broadcom, because they have firmware files in their cvs


can i legally get those files and include them into freebsd port's 
collection? if this is going to lead to too much corporate brouhaha then 
perhaps i should leave it as it is. bcmfw(8) and bt3cfw(8) man pages 
already tell users where they can get the firmware.
