I was in the middle of writing a sample page to create a compeling Silverlight install experience (ie. anything better than the plain Install Silverlight Now button that appears in Silverlight Streaming hosted apps) so I can show how well the user can be guided to install Silverlight for a project we're working on.
As I hunkered down and got ready to hit the code, I find a link to... a white paper and sample code on how to make great Silverlight install experiences.
Well.. that sure saved me a lot of trouble! :P
