Today we releases the Web Services for Remote Portlets (WSRP) Toolkit for Microsoft Office SharePoint Server 2007. The toolkit provides customizable source code to help customers reuse content that resides on other portals. Customers can download the source code and white paper at http://code.msdn.microsoft.com/WSRPToolkit
The toolkit contains two sample implementations of an WSRP producer for SharePoint as well as the sample source code for each. You can also view videos of both sample at the link above.
