there is a use for a program "like" peerguardian but for a slightly different purpose. Not for p2p use but to maybe block all "phone home" programs like adobe,etc, at the same time.
We already have "a" program like that. It's called a personal software firewall. No need to go re=inventing the wheel. -- Some call it muscleA monopoly of sortsBut its just damn good marketingThat got them to court.
