As a baseline, how about just 400 kilobits/second, but: symmetric, under 60 ms latency to 48 states, packet loss of less than 1% for any size packet when not exceeding 400 kilobits/second (to 48 states), latency that doesn't increase under load, and less than 5 hours of downtime per customer per year.
I'm all for the availability of cheaper plans, but this seems to be about ISPs getting broadband subsidies to provide people with less than broadband speeds.
