I've tried to take a look at the "big picture" of ICANN you get when you just try to look at the economic aspects of the various activities in the DNS field. The result was called Domain Name Economics and posted to the icann-europe mailing list.
On a related topic, you may wish to have a look at David R. Johnson's presentation on Why A General Assembly Matters. In this text, he asks about what kind of social contract underlies ICANN, and how the organization was originally supposed to work.
A new version of Strip, the Secure Tool for Recalling Important Passwords, has been announced to the strip mailing lists. It's available for download here (source code). The new version is supposed to fix the password generation vulnerability I discovered back in April. It also brings AES encryption, and an integrated S/KEY calculator for the Palm.
OK, it was slashdotted, but I don't want to lose the link: Drew Streib has published an analysis of the signature relationships in a "full" PGP/GPG key ring. In particular, he looks at the largest "strongly connected" set within the key ring, which consists of about 10000 public keys.
