I think that a a great solution to spam would be digital signatures and encryption. If everyone used, say, GPG to encrypt and/or sign all their emails spam would whither. Here's why:
1) The process of encrypting emails takes a sufficient number of cycles that it is no longer "free" to send out 1 million emails. Suddenly just the process of encrypting the email costs enough cycles that spammers will be limited by a CPU bottleneck. If it was reasonable to reject un-encrypted email because encryption was standard, then voila much less spam.
2) Secondly, even just digital signatures would be an incremental improvement because it gives a good idea (but not guarantee) of who the email came from. It is certainly harder to steal a private key and password than it is to spoof a return address. Subsequently one could black-list the offending digital signatures because unless your friends are spammers, then the signature belongs to a spammer or has been comprimised.
I love KMail from KDE because it makes encryption and digital signatures very close to seamless and therefore makes the solution that I mention above more likely to come about.
I built one for my own research-see the end of the PowerPoint presentation under "A Context for Assisted Cognition" on my home page" . I could have made the form factor about 50% smaller if RadioShack had a better selection of project cases, but oh well...
I can get 5m accuracy (using GPS/WAAS) and can run and record data for about 3 days on end with samples every 2 seconds.
All the data recording is done with a PalmPilot and you can get it from Linux or Windows.
I've fooled around with Finnix , a bootable-CD distibution of Linux. It's pretty lightweight and worked well for me, but I'm not sure how well the networking support is. Anyway, it might be a nice place to start.

Berkeley has a much more sophisticated project that does far more than find exact matches. Most Computer Science departments know about it, and many classes use it to detect cheaters:

If I have a web page with any service that provides web-hosting, I will have my content in the domain name that the web-hosting company uses. For example, a page describing a non-profit educational organization that is hosted by Yahoo!'s free web-page service will technically be under a.com domain name. As such, no one has succesfully dictated my content in this domain name. This doesn't preclude my being excluded from some other domain name, but it's certainly not a very big problem IMHO. How much do people care if National Public Radio is.org or.com as long as they can get to it?
If you play a government lottery you pay the government for the ticket and then when you win you pay the government ~half of what you won back to them. Of course the government doesn't want anyone moving in on this scam.
