"AFAIK the MSOs have not made any provisions for increased upstream over the cable, even if you are willing to pay commercial rates. After all the bruhaha over the upstream limits there was some talk about levels of service with differing price points but I don't know if anything came of it." Generally speaking, you are correct.. especially where home's partners are concerned. But there are exceptions. Some of those exceptions make use of cablemodems which employ ATM, such as CMOT's. In the Palo Alto Cable Cooperative, QoS is assured to those telecummutes who wish to use it, at a price. CMTO at one time used this cable operator as their poster child on their web site, but it appears that they've removed it recently. Such an approach works out very well if the number of takers remains below some threshold, because they are still using standard HFC/DOCSIS spectrum allocations, which are not friendly to the upstream. Where they take some bandwidth and guarantee it to those who pay more, they at the same time take that same amount from everyone else, effectively. That is the definition that is sometimes used to describe QoS. Provide more bandwidth and assurances to those who will pay for it, at the expense of those who cannot afford it or who elect not to subscribe to it. Well, usually, in bandwidth deprived networks...
