It is certainly something we will consider as we refine the roadmap for future versions of the server. We are paying close attention to the HTML5 video/audio capabilities as they unfold in the different browser applications and operating systems. This first round we chose to focus on HTTP Live Streaming from Apple and Smooth Streaming from Microsoft. We feel like this is a good place to start.
We are planning on support live and video on demand streaming to Silverlight. We will log session activity much like we do with Flash. We plan on providing a means to deploy a fully scaled environment for delivering vod and live streaming across a large, multi-server environment.
