I don't think open sourcing Clearview was a viable option, and as things are right now, it seems like we are getting the best of both worlds: the community is still very well served with JPivot and the upcoming PAT, while EE customers get great additional value from ClearView. And I agree on the strength of the platform; being able to integrate an acquired piece of software in a matter of weeks (not months) proves the power of the plugin architecture.
