Scott M. Fulton announces that Microsoft "worked with Apple" for Silverlight on iPhone.
It was an impressive demonstration, once they got it working: H.264 video streaming wirelessly (and slowly, at least during the caching sequence) using Microsoft's Silverlight video streaming, to an Apple iPhone. It's all the more impressive when you realize that Flash video still has not made its way (permanently) to the iPhone, not for any technical reasons we know of...simply because Apple wants to control the video channel for streaming media to its devices.
