Things I'd like to know about Atlas (aka Ajax from Microsoft)

Wow, I am all pumped that sometime during the week of September 12, I'll get to start learning about Microsoft's Atlas project.  Just thinking outloud, here are some things that I would like to know about:

• Everything (yeah, thats a big wish).
• Debugging.  How am I going to easily debug client and server side code in one place.
• Security Integration.  How do I integrate with Forms and Windows Authentication.
• ViewState Integration.  Is it possible to reach into the statebag and get stuff from there.  What happens when I store the ViewState somewhere besides the client.
• Cross-browser support.  How well does Atlas support IE, Firefox, Opera, and Safari.
• Downlevel browsers.  What happens with a mobile browser or some other type of dumb browser.  Do I get some type of downleveling where I can get some type of support for browser that does not have all of the features to make Atlas work?
• Builtin control support.  What types of builtin control support are there?
• Third party support.  What third party companies are building support for Atlas into their controls?

BTW, while I have mentioned that I am going to work on an Ajax for .NET book, I don't know anything more than what I have read through ScottGu's blog.  I'm just throwing out a wish list of things that I have been thinking about over the past several months.
