> Which is a problem. If an ISP chooses to oversell its bandwidth for a given segment of its residential customer-base, then it's already in the business of deceiving its customers. If the ISPs didn't do this (or at the very least provided some minimum guaranteed bandwidth, with or without a maximum "burst" speed similar to what's happening now for residential customers), then they wouldn't be in a situation where they feel it necessary to be the ones imposing QoS settings upon their customers.
It seems that you oppose the existence of residential bandwidth plans and would prefer that ISPs only offer dedicated bandwidth plans. There is nothing wrong with believing this, but doing so would drastically reduce the value of the last mile circuitry for consumers.
My home internet (cable modem) costs $90/month and I get upwards of 120 Mbps (close to OC3 bandwidth) downstream bandwidth. Upstream is about 50 Mbps. A similarly broadband dedicated circuit would cost thousands per month. I'm certainly not under the impression that I am getting (or should be getting) a dedicated bandwidth level of quality with this cable modem, and I think it's fairly ridiculous to expect that ISPs could offer dedicated bandwidth for the sorts of prices that residential consumers are used to paying.
"It seems that you oppose the existence of residential bandwidth plans and would prefer that ISPs only offer dedicated bandwidth plans"
Not necessarily. Like I said above, even having a certain amount of dedicated bandwidth (even as low as, say, 5Mbps) plus a burst to, say, 100+Mbps during non-peak times would be a lot better than the current situation of no guarantees at all. The exact numbers should be easy to calculate: Min = Total / NumHouses, Burst = Total.
All this is still tangential to my main point, though: of that slice of bandwidth the customer can access during peak hours, the customer - and only the customer - is the only person who should be able to decide how that slice is allocated. If my neighborhood's Internet is really busy and I'm left with 1Mbps, then I should have full control over that 1Mbps. Cable company wants to reserve some of my 1Mbps for its half-baked VoIP offering? Boo hoo; my Counterstrike takes priority.
"for the sorts of prices that residential consumers are used to paying."
Cable companies are already overcharging for Internet plans. They can do this because they have all the benefits of a public utility (namely: the local monopolies) without any of the regulation.
So no, I don't believe for one second that the cable companies can't afford to provide at least some guaranteed minimum bandwidth. They just choose not to because they can get away with it.
