Is Rendezvous Sharing More Than You'd Like?

Gropo asks: "I just got an email from my father who has just recently upgraded from OS 9 to Mac OS X on his PowerMac. He's connected to the 'net via Adelphia Cable and shares his TCP connection with my Mother's iMac via Software Base Station. He got a call from his neighbor (also running Mac OS X) who noticed 'My Father's Computer' show up on his network. My first thought was: 'He's picking up your AirPort signal' - alas the neighbor has no AirPort card. The neighbor *does* however also have an Adelphia cable modem. I asked him to scan for available afp:// servers and sure enough, a foreign machine showed up. What's the easiest way (if at all possible) to enable auto-detection for the local wireless LAN (useful for file and printer sharing within the household) yet remain invisible to other people also behind the cable companies' local DHCP box?"

I'm a network specialist for a cable company, the problem is probably that both machines ended up on the same subnet and since there's no router (i'm assuming) it goes out and hits the ubr and just like it would on a lan and shares with your neighbor.
