i'm a little confused about what you want to do. as far as i can make out, you want to get the digital footage from the camera to... both computers? or just computer B? not sure. i suppose what you could do is hook the camera up to machine A and copy the stream over. then, use a firewire cable to connect the two machines, put machine B into target disk mode, and copy the stream from machine A to machine B. or something.
