PeerFactor Provider is a P2P that allows you to legally gain music and games - Windows Freeware. Usually with peer to peer software, you share your bandwidth and can get unlimited access to content available on other PCs from the network.

PeerFactor works in a different way. You install the PeerFactor client and share your unused bandwidth and some CPU with them. They sell these capacities to their customers. And finally you get rewarded with an unlimited music (or game) subscription similar to "Yahoo! Music Unlimited".
