how expensive is a firewire port ?
firewire stuff is THE niche to fill.
most newer firewire devices are not supported if if i understand
correctly.
Just to make a bit advertisement, freebob supports few firewire devices
on the market :)
Generally, I would not recommend to build a firewire based device in any
way. It is has some very nasty features which are hard to get right,
e.g. the LLC is extreme difficult.
