Actually, in europe at least firewire cards are < $20. The abundance of DV
camcorders has pushed the price down.

I was under the impression that the HDSP used the firewire physical layer,
but not the signalling technology, but I could be wrong about that, you'd

The other 1394 devices do at least work with generic cards, even if they
dont use a standard protocol.
