A compelling argument, but Andrew has already stated that " this is not a software, not a client, and not a service.".

Peer to peer for sharing computer power is an obvious benefit over a single server serving many clients, but this would still need some central site to aggregate the data - somewhere that new users can go to connect. (think 'the pirate bay' as an already relevant example).

This will always be the case - regardless of how the future shapes communications.

Think see more along the following lines - telephone directories, Public address books, IRC channel listings, Search engines. All providers of communications have some form of directories or listings - somewhere that everyone can go to find others.

The internet has revolutionised this, sites like facebook, myspace, orkut, whatever, all provide this kind of service, but present it in a relevant format.

Our own websites further serve to act as a filter - they filter out the noise - users of my Dolphin site only get presented with information relative to the sites subject matter - they do not have to trawl through pages of irrelevant stuff to get to the information that they want.

Peer to peer has it's place, and may well form a part of the future of communication in this medium, but there will always be a need for filtered aggregated content - ie websites like yours and mine, in this respect, tools like Dolphin will still form a part of this future and should not be dropped in favor of some fanciful scheme like this.
