dsandler writes "Researchers at Rice University have just released version 0.7 of FeedTree, a peer-to-peer system for distributing Web feeds faster. Instead of polling feeds independently, FeedTree users cooperate to share news updates using multicast in Pastry, a scalable p2p overlay network. FeedTree reduces the update delay for existing RSS and Atom feeds to a few minutes without putting extra stress on the webserver (anyone who's ever been temporarily banned by Slashdot's RSS feed knows this is a real concern). Feed publishers can also choose to push digitally signed updates for immediate, tamper-proof delivery to subscribers. The client software (download) runs on Linux, OS X, and Windows, and works with any desktop feed reader."
