Hi All,
We have just released an add-on Data provider to Data Synchronisation Studio that allows you to connect to MS CRM 4.0 and synchronise your data between a variety of data sources such as MS SQL Server, Oracle, MySQL, SharePoint, OLEDB, ODBC etc.
We have an how-to article up on the site that explains how to synchronise an entity with the new CRM 4.0 data provider.
