Vapourware? What's wrong with IEEE-1394, already capable of up to 3200
Mbit/s and able to transmit uncompressed HD video at this speed? USB
suffers from loss of speed as soon as you have more than 1 item of
hardware connected to a bus, because of serial handshaking with each
device. With USB-2, if you have just a keyboard and a mouse connected,
you don't have enough speed left to transfer even DV (SD video
compressed ~10 x) on the fly. With IEEE-1394, you have none of these
problems.
