It is fine if i have to pay for more bandwidth/allocated bandwidth.
As long as everybody has to pay the same price for this. Because then I (as a customer or provider) can compete in a special area with google.
If only companies who can affort their own ATM networks and are powerful enough to push anybody else to give preference to their traffic, then nobody can compete.
Which is why i think a mandatory split of companies into branches and trading of bandwidth of all kinds (guaranteed, allocated, and opportunistic) on a stock marekt would be appropriate.
And actually: yes, there is traffic, which I as a consumer need with higher priority than other traffic. I just would appreciate if I have the choice.
