Sky appear to have listened and published instructions and software on how to remove the p2p aspects I discovered were running left behind when you uninstall their broadband application, Kontiki's kservice.exe. Interestingly they list other programs that will stop working, including
BBC iMP, Kontiki Delivery Manager, Cinequest Delivery Manager, AOL Hi-Q Delivery Manager, Palm Support, and the Open Media Network.
It does make me wonder if any of the software listed above is honest about what is installed and why on earth the Kontiki aspect cannot be cleaned out as part of a normal uninstall.
