We have the same problem out here in Australia with ISPs selling
"unlimited" accounts, but they really aren't unlimited in the
truest sense of the word.

The cutest idea I ever saw (and I'm not sure how well this'd
scale on a cable network, but ..) was adaptive bandwidth
limiting. One ISP tried bandwidth limiting each dialup customer
based on how much bandwidth they had used over a calendar month.
If you fell inside that top 1% which used 50% of the network
resources, you soon ended up getting a trickle of traffic.
Local traffic (for example, gaming, or local IX traffic)
wasn't affected by this pipe.

Personally, I think that would be wonderful for Residential
Cable/DSL services - there's only going to be a (relatively)
small number of your userbase that will ever be affected by
the bandwidth limiting, and you're still providing "unlimited"
connectivity to whatever you deem as "local" ..
