StepTwoDesign makes a good point (with a strong :-) ) about the use of a groups/department/projects use of a collaboration environment (could be ) in two different ways:from
1. the use as a 'shop' front-end (publishing like) for information to share with others outside the group
2. the use of a 'workshop' back-bone (collaboration like) for information to work on and change within the group.
Interesting approach that is worth further investigation. Metadata is a very critical component of it all.
