Intranet Governance Policies

It strikes me that when intranet governance is mentioned by intranet professionals, they are generally discussing overall governance structures - i.e. intranet boards and committees, however, I'm interested in finding out some more detail on more granular detail on intranet governance and auditing issues.

For instance, I need to provide an auditable structure of user access both to our content management system and to the folder permissions on our network attached storage which acts as a document repository. If I roll out any collaborative tools such as a blog, wiki, bbs/discussion board, project management comment tool, instant messaging client etc. I will also need a clear governance structure for this also i.e. a set of defined behavioural norms and guidelines, as well as moderators/discussion facilitators.

Anyway, my conscience on these matters was piqued when reading through Mike Gotta's piece that I blogged about on 5 May 2004, which was very focused on the business implications of social software. So, I'm hoping for some responses - what governance issues have you come across related to intranets, and how have you solved them? I'd be interested to hear everyone's comments.
