There are some parallels. I'm not sure the constraints are close
enough to want to join the two things. Audit trails will have a hard
'no rewriting history' requirement (with discussion points around
'what do show if a related object is renamed or deleted'). Activity
walls have a much more mutable nature: hide things that aren't
interesting, show things that interest the user, and evolve to match
the users desires. Its possible that an audit trail could pun as the
normalised datastore for walls/notifications with a denormalised view
layered on top. Theres also a difference - e.g. when reviewers are
added to a merge proposal. the new reviewer is told directly, the
project knows the reviewer was added, which is two separate views on a
single action.

Its certainly something to bear in mind anyhow :)
