What does it feel like to download an entire HD movie in a matter of seconds? Your best bet is to ask the group of scientists that did the equivalent of that recently.
The Japanese scientists that performed this feat were a part of the Internet2 Consortium. They managed to clock speeds of over 9.08Gbps over the internet to a facility 20,000 miles away.
That kind speed in the wrong hands could lead to....lots of porn and torrents being downloaded in a matter of seconds. I'd be happy to actually get realistic download speeds around 1-2Mbps. My connection can handle it just fine, but I rarely ever find anything that downloads that quickly.
