Sharing Is Good
The big national broadband ISPs have very strict policies preventing consumers from setting up servers or sharing internet connections. One ISP that sees this as an opportunity is Speakeasy Networks which actually encourages sharing connections and setting up servers on their DSL network. Of course they do charge a bit more, but they seem to be very market driven by catering to customers who need a little more from the broadband ISP. The big guys could learn something here. Rather than saying no to your customers, figure out how to say yes.
