Still got my authentication problems with performancepoint in claims using an embeded SSRS report. Seems even MS cant solve the problem. Still seems strange to me that although SharePoint is claims aware the SSRS report server is not, and we can't use the SharePoint reportviewer proxy through performancepoint.
Although I think SharePoint and perfpoint have come a long way, I think there is still work to be done around authentication and simple options for PPS reports like the ability to change the colour of a chart!
+Ian Herndon I'm working towards extending our BI capabilities by greating a G Maps web part with BI in the pop up infowindow of the markers. This will then provide a connection to a performancepoint dashboard/report. I'll post some images/samples when its up and running.
