Joe,

I'm not really all that up to date on this aspect. The best suggestions I can give is probably to suggest that you read Chapter 3: Component Sharing in the Application Specification for Windows 2000 for Desktop Applications, if you already haven't. It's in the Specifications section of the MSDN Library. The chapter will refer to you to "Implementing Side-by-Side Component Sharing in Applications" via a URL.
