So, take a deep breath, and read things slow.

The Silverlight 1.1 Alpha is going to have the same CLR as the desktop version that allows you to leverage your existing .NET skills in VB.NET or C# to build Rich Internet Applications (RIA). You will be able to write .NET to run in the browser on the client side of one of these Rich Internet Applications.

So, you’ll be able to run .NET on for example a Mac!

That just put Silverlight RIA’s in reach of any development shops that are currently doing Windows Presentation Foundation (WPF) with C# or VB.NET.

And,  there’s support for Silverlight in VS.NET Orcas with a free download called the Silverlight Tools Alpha.

Now, goto line 1 of this article, and read again.

Some news about Silverlight Streaming

Silverlight Streaming is a storage and video delivery service that enables developers and designers to upload their application to Silverlight Streaming and then deliver this application to any website globally.

Silverlight Streaming will provide 4GB of free storage as well as unlimited outbound streaming at 700 Kbps. For the first year, the service will be free. As the service moves out of beta it will be offered as part of the overall WL Platform offer, with continued 4GB free storage and free streaming up to 1 million minutes of streaming per site per month. Once a website goes over the 1 million minutes of streaming threshold, the site will have the option to take ads and revenue share or pay a small fee to help cover MSFT costs.
