Ah.. So, if I understand correctly, ethernet like behavior is in
effect emulated with firewire "messages", instead of firewire
completely encapsulating ethernet frames?

I always reckoned that the arp protocol over firewire contains some
sort of translation from the firewire addressing to an ethernet like
addressing scheme, and that host addresses are provided for by
address allocation faries.

Come to think of it, now that I'm looking, the fw based interfaces
don't have a MAC address [of the type i'm familiar with], instead
the hardware address is 8 bytes on OSX, and 16 with the bottom half
all zeros on linux.

*sigh*. It could have been fun.

Thanks for your knowlege and input!
