@JC - I believe that hosting mode really is intended for large-scale hosters that typically have the resources to build custom provisioning tools which make the EMC obsolete.
It is not really usable (nor intended) for smaller-scale needs which will hopefully be well met by this new option in SP2.
I still feel that the timing of the announcements re:2010 were poorly handled, as many of us had already migrated our supported 2007 ALS environments to 2010 LONG before any mention of incompatibility was brought out on Dave's blog. These environments will hopefully be considered when documentation is provided on "getting back to a supported state" in order to properly migrate to SP2 ABP.
