You didn't ask that but I can't resist: Compared to PCI performance 
every firewire i/o box looks meagre. No DMA. Interleaved transmission, 
so bandwidth trouble hits all channels right away. Firewire was not 
made with multichannel audio in mind and it shows.

RME's Fireface manual reads like a confession. Problems all over the 
place. They built a thing called "Safety buffer" into it. Gives you a 
minimum round-trip latency of 48 frames in + 48 frames out + 64 frames 
safety on the way out (3.6 ms/44.1khz). Not bad but not good either me 
says.

Why everybody wants firewire i/o just the same? I don't know.

I wonder if developping a free driver is worth the pain. M-Audio, RME 
etc. seem to have made it clear that they themselves won't do it.
