Just closing out the loop on this thread, i did test out the cheap $10 network tap, since you can only monitor traffic one way (you can pick which way), when I was monitoring the traffic from the switch side of the tap, I was able to pick up zone/mobs and stuff moved around on the map except my character. Since showeq wasn't picking up my client data (packets being sent back to eq), it doesn't show the cirlce move around or direction or nothing. So I guess in a pinch, you could use it to check to see if named are up and where mobs are, but it only provides limited function.
