Can I use the same physical machine (with as many ethernet cards as

different network cards at the same time. And yes, I know that I can hog 
the sensor, but the networks are going to have little traffic (at least 
right now!).

It should be doable, but don't forget to secure the heck out of that
sensor. Like:
- disable IP forwarding
- don't assign IP addresses to the "sniffing" interfaces
- perhaps configure those interfaces to not even answer ARP requests
- etc.
