somehow a nice idea, i only see one problem:

firewire and usb audio devices are mainly used with laptops, whih 
normaly have only one ethernet port. if you have a desktop, you could 
also use a pci audio card.

what about usb 2.0 audio cards? has firewire any advantage? big 
disadvantage with firewire for x86 laptops: they mostly have 4 pin 
firewire port, so always need external power for the firewire audio device.
