Be less of an asshole, it’s free. I’ve been sniffing packets from cable modems since the 90s. I even remember the mac address of my first network card - 00a0cc52cac7, because mediaone gave out persistent hostnames based on your mac address before they were bought by at&t. I once putty’d into my machine from Katmandu just because I could. Incidentally, when I called at&t support to find out if this would continue, their support rep had no idea what I was talking about, and after I mentioned mac addresses, he suggested I call apple.
