In short, no. 

I promised to follow up on this question that was asked in my What's new in Visual Studio 2008 for Web Developers webcast this week.  The ASP.NET Futures "contains an early developer preview of features providing a wide range of new functionality for both ASP.NET and Silverlight. The Futures release includes early experimental versions of features currently being considered for future versions of ASP.NET and the .NET Framework." (from http://www.asp.net/downloads/futures/)

Although the ASP.NET controls in the Futures release are not ready for prime time, I definitely recommend taking a look at them and providing feedback at http://forums.asp.net/1127.aspx.
