Hi
I have heard that Microsoft are changing their view on how SharePoint should be used with Moodle. Rather than the 'bring Moodle in to SharePoint' concept they are now looking to use SharePoint as a tool to support Moodle. I believe that this is being done by using SharePoint to 'push and publish' resources to the Moodle classrooms enabling users to update documents 'directly' rather than having to go through the 'change, save and upload' routine. So it maybe that it is not so important to 'bring Moodle to SharePoint'. I mean all you really need is a link to the MyMoodle site.
Cheers
Stephen
