Q: How does Microsoft Dynamics NAV integrate with SharePoint 2010?

A: I'll be the first to say that I know virtually nothing about MS Dynamics, but the question was asked, and as it happens the MS Dynamics NAV team have a blog post entitled "Microsoft Dynamics NAV Compatibility with Microsoft Office 2010 and Microsoft SharePoint 2010 - Microsoft Dynamics NAV Team Blog - Site Home - MSDN Blogs", which outlines some of the compatibility features, e.g. similar user experiences, ability to query Dynamics ERP & CRM databases via SharePoint BCS, which in turn allows synchronization of MS Dynamics information to Outlook & SharePoint Workspace, etc., etc.
