A Spam-resistant Email Network

I am really fed up with spam. Yes, I am behind a spamassassin filter, and it is getting less and less useful with every passing day. Many other interesting ideas (including ji's patent) have failed to catch on and provide significant relief. In a recent column in IEEE Spectrum Robert Lucky expressed his yearning for the days when email was only used by the elite in the know, the select few who "were on email".

If spam has decreased the utility of email to the point where it is comparable to the time when only universities and research centers had access to it, we may well be at an inflection point where a new spam-resistant mail system can be setup and succeed.

I have outlined the principles of operation behind such a system in a document I have placed at http://www.spinellis.gr/nospam.pdf. I will appreciate comments; feel free to share the document (but only via the URL please).
