And you know it's gotta only be a small percentage of users that are using a large amounts of bandwidth on a regular basis. So either they really are having issues in supplying enough bandwidth for everyone without congestion, or they are just greedy and are wanting to use this as an excuse to charge more for their service. Either reason would support my argument that lack of infrastructure and/or greed will be the reason why this won't take off any time soon. It will cost a whole lot of money to upgrade our infrastructure to where it needs to be to supply the bandwidth needed, and we all know that the corporations aren't going to stop being greedy any time soon.
I am a Time Warner customer that uses their Road Runner service, and I can tell that my internet seems slower in the evenings, most likely due to the higher usage when the kids are home from shool and are online doing schoolwork, playing video games, on youtube, myspace, whatever. Now imagine what will happen when all the kids are online, and the parents and many other people are trying to stream/download movies or shows in the evening. There would be way too much congestion, and everyone would be complaining about slow service. I have the highest plan, turbocharged internet and it is slow at times, so I don't see how people upgrading their service plan would help either.
