The early cable modem I had (LanCity, 10Mbit/sec bidirectional!) was a
very lightly filtered bridge.  One saw all the ethernet broadcasts
(mostly arp-requests) and arp-reply's but none of the other unicast
traffic.  My current cable modem (RCA DOCSIS 215 128kbits/sec-uplink,
1.5Mbits/sec down) is a much more heavily filtered bridge.  One only
sees ethernet-level broadcasts.  So in summary, mine is not really a
VPN, but its not an easily snoop-able system either.  (Your mileage
will almost certainly vary.  Folks running PPPoE on their cable modem
may not every see other machine's broadcasts.)
