Microsoft Silverlight

I am at MIX 2007 and writing a quick post inbetween classes.

Very excited about what I have seen so far regarding Sliverlight. Some things I like:

• Manipulate the DOM using Silverlight.
• Write in C# - which is way better than Actionscript ;-)
• Create custom Silverlight controls
• Light plugin that installs really fast!!!
• Silverlight^TM Streaming by Windows Live^TM  rocks!

My only concern is how can we guarantee that the client will install the plugin? There are organizations out there that have locked their active directory using group policies. How can we convince the IT department (those that are concerned about security) to deploy this plugin in across the directory? In addition, public access terminals are also generally locked down which prevents the user from viewing a page developed using Silverlight. IMHO, MS should put the word out there about why this is a safe plugin to install.
