Liquorpuss, in answer to your comments, there already is a sort of freeloader control in place. Groups (of those willing to share files) have set up SUBNETs within gnutellanet. Subnets that have several hundred people (or more during school hours) have plenty of speed and files. These subnets have people who genuinely want to exchange files. Because they are subnets, they don't appear on the main gnutellanet search results... Their results and gnutellanet downloads are available only if you have access to the subnet...
