If you're deploying (or considering) Office Sharepoint Services 2007 in a regulatory environment, then there's a new white paper on Compliance Features in the 2007 Microsoft Office System just been made available for download.

It has somewhat of a US bias, but doesn't exclusively limit itself to US standards and at least gives a namecheck to the Data Protection Act (1998) and Basel II. The bulk of the document, however, isn't regulation-specific, but is a more general look at the typed of compliance and the MOSS functionality which may be pressed into service to aid compliance.
