For the enterprise also there is a need to think about the application. There are apps that need low latency (e.g. fine grain location based CRM now and vehicle to vehicle safety communication in the future, maybe collaborative video edit too) and those that one may consider as "batch processing" where several seconds is fine. Agree that the strongest latency is going to come from the home gaming market, although this may be considered a commercial entity in the future, the game developers and owners of the on-line servers make money out of this and the model of remote processing for some of the interaction is being seen already. This is an extreme bandwidth, low latency, money making, application.
Broadband in the United States is largely an embarrassing topic. Service penetration leaves 19 million in the information dark, and prices are not going to go down if the telecoms get the full-scale deregulation they look for. For more information, click here.
