hi Chris.

that's interesting.  i was wondering about the difference between a single
machine node with 4 PCI cards and a single machine node with 1, 4headed
capture card on 1 PCI slot (e.g., Winnov Videum 4400 ;^).

i'd assume that the 4 card machine would have the combined bus speed
advantage.  but that's an assumption.

'anybody have a learned opinion on that?
