There are at least two ways to prevent such sniffing from being
effective:
1. Prevent users from putting their cable "modem" devices into (their
equivalent of) promiscuous mode.
2. Encrypt all cable-modem traffic, with separate keys for each device.
Unfortunately, your apparently positive experience offers little
reassurance that *all* cable ISPs enact one or both of these measures.
Other anecdotes indicate that some do neither....
