Silverlight Streaming

You may or may not have heard of a new service from Microsoft called Silverlight Streaming.  Its an interesting service with the ability to stream video through the Silverlight media control.  It also seems to be a mechanism for Microsoft to compete with Google in the area of user video. 

Recently I have been playing with producing the podcast in Flash.  As a result, I have been getting needled because I don't have it available in Silverlight.  Well,  I checked out the Silverlight Streaming service. Here's what I have discovered so far:

• Is there an easy way to add the necessary control to Community Server?  I would think so, but I haven't experimented with it yet.  any info on how to add the control would be helpful.
  
• The free silverlight streaming product only supports upto 10 minutes of video.  Well, the podcast can take over 10 minutes, so thats out.  I thought that this was interesting, however, I looked at this from the standpoint of the marketplace and it made complete sense.  YouTube has a 10 minute video restriction also.
  
• There will be a for-pay Silverlight Streaming service.  That sounds interesting, but how can I then support direct download of the podcast?  What about support for the iTunes podcatcher.
  

Anyway, just a few things I thought I would throw out.
