An update on progress around Exchange 2010 address list segregation documentation

Dave, the statement I made was incorrect, what I meant was Microsoft provided a hosting whitepaper for a certain period of time during the version of exchange that was out, until extended support kicked in for each version. Hence while I am assuming the 2k7 ALS hasn't been pulled yet. The important question is when the ALS whitepaper is posted for e2k10sp1, will it have complete migration path methods step by step to go from e2k7 both internal org hosting and commercial hosting? The concern to me is it looks like MS Dev created an opportunity for companies to branch out and create a business to host other companies exchange organization from their one exchange org. Then over the past 10 years they have slowly drawn it in to where getting the latest version of exchange will require Microsoft Hosted Exchange through Microsoft will be the only option. It mainly seems like Microsoft has created a market for hosted Exchange, and as they upgrade they take away capabilities to where hosting through Microsoft's next version of Exchange maybe the only way to have ALS.
Because I doubt Dev will allow customers to have environment control , aka delegate permissions when MS is hosting it. I always read your blogs before I post, I was just wondering why the whole whitepaper wasnt on there yet.
