One notable thing about per-bit pricing, as well, is that once one provider really rolls it out and pushes it at a low cost, it's bound to become a surety. Suddenly the provider with per-bit billing will be able to steal all of the low-usage customers, while leaving the expensive near-saturation customers at other providers... effectively raising their cost per DS1... As to the merits of per-bit pricing.. I could certainly see myself purchasing a lot more bandwidth if I could use it on demand, even with the possibility of someone deciding to smurf me. And think of other positive effects-- there will be real economic forces urging customers of providers not to be smurf relays, etc. Mike -- Michael P.
