The new (and final) Beta of Visual Studio and the .NET Framework has been released. These are 2008 and 3.5 for folks that keep track of version numbers. 

Visual Studio 2008 Beta 2 and the .NET Framework Beta 2  

A cool part about the beta for developers is that you can use the Visual Studio Team System product.  It has so many cool features.  I actually use Visual Web Developer Express on my home laptop for ASP.NET and web pages and VSTS on my home desktop.

I have been working with the folks in Microsoft Research Cambridge for the last several years as they have investigated "peer assisted download technology."  They are doing a 4 week test and, in my experience, is a very easy way to get the ISOs for VSTS.  Try it out.

Microsoft Secure Content Downloader is a peer-assisted downloader for downloading select Microsoft CTP's
