FYI: video stops at 10:12 repeatedly.
It really is awsome! I'm not aware of official release info, but it's expected that sharepoint server license will be required for Access Web Services. I agree that some support for access services should be in wss (sharepoint foundation), as it will surely show small businesses the power of moving Access Apps to the web.
On a positive note, it appears that External Lists in sharepoint 2010 may be available in sharepoint foundation 2010.
Keep up the great work guys...nice hat!
