Algorithms can't be copyrighted, only specific implementations of an algorithm. Algorithms can (unfortunately) be patented, and this would have the effect you describe (prohibiting independent recreations), but I don't know if the FastTrack algorithms are patented. In every case I have seen about a FastTrack-compatible program being shut down, the program in question copied code directly from Sherman Networks' popular client for that network, and the question of patent issues never came up. - Josh Triplett
