I am almost dreaming of spam prevention ;-)

I have just written some shell scripts to spam-tag my mail
based on ideas from Paul Graham.

Right. Gnunet definitely needs working spam protection. 
Existing file sharing networks are spammed too. People are
now using them with externally provided SHA-1 keys.

Every big public system with search capabilities (file
sharing networks, usenet and www search engines) and
all open messaging services (email, icu, sms) get spammed. 

IMHO the solution to the spam problem are trust metrics.
This basically solved the problem on the web (google, page rank).
