Sounds great, but where can I find a firewire interface that will let me

How do you think a bus powered USB device does it? USB bus power is 5V.

my firewire alarm triggered here...
What latest version are you talking about? The 1995 version (400Mbit/s)
can handle >200 channels at 48k, providing both phase and rate accuracy
for all channels throughout the system. There is not a doubt about the
fact that FireWire is technically superior to USB in general, and
definitely regarding audio.
A more recent version (1394b-2002) has commercially available products
at 800Mbit/s (400 channels), and specified up to 3.2Gbit/s.
Let me give you some arguments pro firewire:
* globally available clock (relative AND absolute timing)
* guaranteed bandwidth
* (1394b) support for redundant connections
* (1394b) optical fibre support
I could go on for a while, but it's not really worth it. The only
'superiority' of USB is in the cost department.
