It runs on IEEE 1394 (Firewire) which is already shipping 200Mbit/sec and soon to go to 400 and 800Mbit/sec. Like USB, it has simple cabling, power, etc. The networking seems extremely swift (I haven't really benchmarked it) But only 63 devices per segment :-( Move over PCI buss. You're slowing us down.
