If I know MS, they probably created JavaScript callable stubs for the .NET components already in the OS. This is the same way JScript cheated by calling ActiveX components that shipped with the OS and Office. I would be surprised if MS really embraced web standards. Or we can expect a portable Silverlight runtime which brings ActiveX to non-MS platforms (like Flash, but from an actual tool vendor. Adobe is struggling being Sun and Pixar at the same time; they're speaking to a wide audience with diverging interests)
