GigaTribe is a fascinating new addition to the filesharing world. Its a service that coordinates the linkage between your computer and others, but hosts no files, does not keep track of files exchanged. Even more interesting, you create your network of trusted file-sharers. That more or less prevents massive illegal file sharing- at least so far as I see at the moment. But does allow safe, private file sharing.
Powers that be won't like this. Wonder what happens.
