Summary of laws related to auditing and logging

Hi all - 

I've just finished a stab at a summary of laws and standards related to IT
auditing and logging:

(never mind the name in the URL; the article developed a bad case of scope
creep). 

I'd love comments and additions. In particular, I'm nearly entirely ignorant
of the current status of such regulations in parts of the world other than
the U.S. I'll be seeing what I can turn up with Google, but contributions
from better-educated list members would be much appreciated. Especially if
they include URLs.

cheers - tbird
