Not another doctor wrote to mention a PC Doctor article about the Sky by Broadband service. In addition to providing access to the internet, the service also helpfully downloads and installs the Kontiki P2P service. From the article: "What this really means is that Sky in all their advertising are making out that you are downloading content directly from them rather than other users. Also, the P2P link continues to run in the background after you've shut down the main application, eating up bandwidth by allowing others to download the files from your PC. Kontiki also collects and sends back to Sky a lot of information about your PC. There is no mention as to how this data is protected from unauthorized access, however, initial examination with Ethereal seems to show that all data is at least encrypted during transmission."
