I have a few questions.

Let's suppose i wanna test NIDS/NIPS with some tool. I picked up tomahawk from bt, but i need 3 eth interfaces. My bt is installed on my laptop, and i still need 2 interfaces. Any suggestions for additional hardware (usb, PCMCIA) or some other (probably better) software? Or, can i install bt under vmware and add 3 interfaces, plus if i want to test gigabit eth, i would probably use few laptops with bt under vm...?
