PFX in .Net 4

No, I'm not going to the PDC, much to my dismay, so I have to live on the crumbs we'll get from blogs. 

PFX will be a part of the .NET framework 4.0.  This is good news!  I have to wonder, though, if this will make it to Silverlight and the Compact Framework?  I am working on some Silverlight performance benchmark stuff and was contemplating porting some of my own work just to see how much effort it would be.
