CNN.comLive_2.5.gifThe blog Windows Secrets reveals something millions of CNN.com users who watched the inauguration on CNN.com Live probably did not know: “that their PC was used to send the video to other PCs, too.”

The blog goes in to a lot of technical detail, which we won’t get into here, about how this all happened. CNN.com acknowledges they used a peer-to-peer (P2P) application that uses your Internet bandwidth rather than CNN’s to send live video to other viewers. The technology was intended to make the CNN.com Live video faster and better.

Mike Wise, group technical adviser for platform R&D at TBS says the network selected the most considerate software for the job, something called Octoshape Grid Delivery.

Windows Secrets concludes that while Octoshape, which may now be on your computer, isn’t a threat, “I personally would rather put up with a slightly jerky video than run an application on my PC that’s sending God-knows-what to who-knows-whom.”
