My previous company built technology in this space, based on Squid, and some custom tools. I vividly recall competitors making bold, outlandish, claims like these on a monthly basis back then. None of them ever came to pass. They required too much infrastructure build out, too much cooperation from ISPs and website owners, and the companies behind them demanded too much involvement and too much money from all parties in the chain. There was a CDN rush back then, too, and only a few managed to raise enough money and build out fast enough to be successful at it. This kind of technology requires a build out similar to a CDN, but with far more involvement of parties that are very unlikely to have an interest in being involved.
I've had long conversations with folks at Akamai, Red Swoosh, and many others, in this particular area...and it's astonishing how much money it takes to build this stuff out, and finding profitable ways to build out small (making it useful enough to make money on without first spending millions and signing on dozens of ISPs) is very difficult. I just don't think there is that much VC money floating around right now, even if (big giant if) they've actually figured out technology that works on the scale they're promising.
