What happens when things are deleted? An audit log needs to stand by itself 
as far as possible. I think Tom was effectively saying we should, between 
any set of changes, be able to do a diff - as with CVS / Subversion. Using 
an audit log you should be able to reconstruct what a group (including 
membership and privileges, looked like at a point in time - in case of a 
dispute can you show, retrospectively, whether a student had access to 
online course materials when they were supposed to hand in some work?
