Allow the SSIS Data Profiling task to connect to non-Microsoft SQL Server data sources. I understand their is a technical dependancy on creating objects in a Microsoft SQL Server tempdb - this could perhaps be accomodated by a separate Connection Manager and a generated Data Flow Task to copy the source data into a tempdb table.
Data Profiling against non-Microsoft SQL Server data sources would be a hook to introduce Microsoft-resistant sites to the benefits of the Microsoft BI stack.
