Like the internet itself, Outfoxed is de-centralized. An informer's page can reside at any valid URI. Outfoxed can upload files to any FTP server, or to specially configured HTTP servers.
And for that matter, the information can be read and used by any program, not just the current Outfoxed Firefox extension. If the idea of trusted metadata catches on, there could be many different trust aggregation tools, just as different browsers can read the same HTML files and different newsreaders can read the same RSS files.
