Re:Here's the patent (Score 1)

I'd have to agree that it is already an existing concept, implemented to some degree or other in many software packages. I wrote docs for a product that could do this 3 years ago. I think it's dead now, but it essentially allowed all of this, including the permissions. Curiously, many features of Lotus Notes also could fit within the parameters described... I think they'll have a hard time enforcing it.
