I've heard of this from others as well. It seems to be technically
feasible, but I am curious about the social aspect: would ISPs actually do
this? Would customer's find it acceptable? (given it still locks them to an
ISP, now to two of them.)
In fact, this is technically feasible right now with IPv4. Does anyone know
of a pair of ISPs doing this?
