Is there any such thing as a "genuine" copper passive tap at 10g? I was 
under the impression that it was impossible, given the differential 
signalling, and such devices at 1gig are invariably powered.

We've used ntap optical taps - they work as advertised, and there's a 
little rackmount thing that can take 3 of them. We specifically use the 
two-channel one to mirror a 20g port channel.

For analysis, we use a server with 2x 2port 10g myricom NICs and gulp ;o)
