distributed architecture....

hi... i'm contemplating a project where a number of websites would communicate with each other via some network of round robin/distributed servers. Each 'client' website/app would be considered to be a 'node' of the overall network, and be able to upload/download information to the network. The master servers would maintain the information, such that if a request for information came from one of the 'client' sites, the master server would shove the information back to the client for display. the overall goal of the project would be a way of allowing a client site to 'share/exchange' information with other client sites within the network, and to allow the content of a given client site to be influenced by the content of other sites within the network... has anybody heard/seen anything like this...?? in searching google/sourceforge/freenet/etc.. i can't find anything that's similar, or that could be used as a starting point for the architecture... the closest i can find is the open source gnutella/limeware p2p app structure... thanks bruce bedouglas@earthink.net
