Not if he's using private IP addresses on his 'local' LAN (10.0.0.0:8
or 192.168.0.0:16), since no packets destined to those addresses will
get routed through the internet.
You might be subjected to attacks from someone at your ISP, depending
on how your modem is configured, but that is unlikely.
You're worst problem is going to be the waste of network bandwith and
the complexities of running two subnets on one cable.
