Diki is a peer-to-peer (or better: friend-to-friend) network for social semantic web application. Think of it as an instant messenger program for social networks like del.icio.us, bibsonomy, citeseer, facebook or studivz. Unlike those social networks, diki does not have a central server that stores your private data. The idea of diki is to create a social network that respects the users' privacy but giving them all functionality that server-based social networks have. In the current release you can create bookmarks, tag them and invite friends. Then you can search for bookmarks in your friends-network.

Bandwidth is a problem for anyone hosting big files. As soon as your music, mp3 blog, or movie gets too popular, either your site goes down or you get hit with a huge bandwidth bill. Worse, the cost and hassle of distributing large media files means that the internet isn't living up to its potential as a democratic medium. Dijjer solves this problem. What distinguishes it from similar P2P tools (like Bittorrent) is how easy it is to use for publishers and users.

The YACY project is a new approach to build a p2p-based Web indexing network.
