I saved the installation files for Cloudmark's SpamNet, and the latest beta release still connects to Cloudmark's servers. (in a limited fashion, of course). Anyway, it fails to filter email very well now.

As I recall, it worked by having client computers calculate some sort of MD5 checksum or hash code or something for each email, and send that to the server with a "spam" or "nospam" tag. Then other clients would download these statistics from the server and filter spam accordingly. If the filtering was correct, the second set of clients would then send something to the server to improve the statistics, if not, they would send something to correct said statistics.

Couldn't something like this be implemented using bittorrent? Or a variation of bittorrent?
