The SQL Server 2005 Feature Pack is freely downloadable and contains a set of useful tools for SQL Server 2005: many items are for compatibility issues (DTS/DSO/DMO backward compatibility), but there are data mining viewer controls and JDBC drivers for J2EE developers. An OLE DB provider for DB2 worths another mention.
