IDS taps

Tim,

I know of a few TAP outfits

NetOptics:

I have some hands-on experience with these.  Full duplex taps--splits data 
streams into RX and TX, meaning they have to be reassembled or monitored 
with two NICs.  Their product may have evolved since we purchased ours.  I 
deployed four of these for different data streams and piped them to a 
managed switch with a SPAN/monitor port for aggregation.  This works fine 
for us for passive monitoring.  Our network segments are all pretty low 
traffic.   Cost for a 100mb copper TAP I believe was around $800 each.

Datacom Systems:

Not as familiar with these, but Google popped them up.

and

Critical Taps

Reputable brand, have multiple tap rack appliances but prices are premium.

I believe at least one of these companies permit multiple monitor ports on a 
single stream of data.  I think they call them 'Regeneration Taps".
