@All
The Apple firewire licensing is for the hardware only. IIRC, they get $.25 (split between Apple and the other firewire partners) per computer with firewire ports. Software doesn't have to be licensed.
@Acill
Are you sure the ADC usage agreement allows you to use their source freely? (I haven't seen the source in question, and I couldn't find your link, so I guess it could be GPL)
