Glen,

I am on this quest too and I think my blood pressure has been raised by it. I just returned home from an all day event with Scott Guthrie, Hanselman and Palermo. It was great, but with all the talk about open communication between systems it seems as though SharePoint has been left out in the cold.

My current quest is leading me on a journey to solve the following: Host an external website in a PageViewer webpart and somehow pass credentials and parameters to the external page. It sounds funny that credentials need to be passed, but it’s true as if the user has “logged on as a different user” the fact of this exists only in the session state. The session state is not passed on to the PageViewer web part. So, I have to use a content editor web part on a different page which will use JavaScript to call the web service to get the user and then call the PageViewer page with the credentials on the uri.
I have been frustrated at every turn to make this happen. Have you had any success in this area?

Thank you for this very useful article. But I had difficult time navigating around your site because I kept getting 502 bad gateway error. Just thought to let you know.

This is great example, but what if you want to execute outside sharepoint? How can the code pass credentials?

Any hints would be more than welcome. TIA!

I would like to know how you would call a web service to return the items displayed in a list to be comsumed by the Silverlight APP:

It currently only uses a data.xml file which is static and therefore of not very extendable? Any clues?

Actually you could even reference it at google and not even worry about downloading it:

The prototype javascript library is the only dependency. It contains all functionality needed to make Ajax calls. In fact, you could completely do away with Prototype if you wanted to write your own XMLHTTP requests. Prototype is just a convenience.

You can upload prototype to any document library anywhere and then reference it in a CEWP like this:

But there is theoretically a way to do this without the library…

thanks again for all your help…
