Tor is something different. Tor tries to patch the architecture of the web, which is essentially broken. The web as we know and use it today was never designed with things like privacy and security through end-to-end encryption in mind.

What the peer-to-peer architecture of projects like MaidSafe do is they abstract content and services away from (physical) web servers. Just like with BitTorrent, you just want to see the latest movie or cat video and you don't (want to) care if it's located on a server called "youtube.com" in California (or "fuckit8df9zs8dfz9s.onion" for that matter). Here it's rather that content, media, services and also "apps" will be searchable by tags and names (namecoin?) and be streamed to you through peers in an encrypted P2P cloud.
