The weak link for any network is going to be the bottleneck at the server, followed closely by the throughput of the transmission medium. DSL wireline services still predominate the main modes of operation, and our infrastructure to support a significant baud rate increase is just not there. We are way behind a lot of other countries, so maybe "The Grid" will work in Japan or Korea or France, but not likely much improvement here for a long time. Wi-Max may be the next big juggernaut, if we can get enough municipalities behind it. We need at least a blanket 1 gigabit backbone if we expect to accomplish anything like the claims they're making with the new protocols.
