Just an FYI that the Microsoft Assessment and Planning Toolkit 3.2 Beta is now released. Microsoft Application Virtualization (App-V) is covered so this should prove to be an invaluable tool as you plan your rollouts.
The Microsoft Assessment and Planning (MAP) Toolkit is an integrated platform with tools and guidance that make it easier for you to assess your current IT infrastructure and determine the right Microsoft technologies for your IT needs. It offers easy inventory, powerful assessment and actionable recommendations for Windows Server 2008, Windows Server Hyper-V, Virtual Server 2005 R2, Microsoft Application Virtualization (formerly SoftGrid), System Center Virtual Machine Manager, Windows Vista, 2007 Microsoft Office, SQL Server, Microsoft Online Services, and Power Management. The popular Windows Vista Hardware Assessment readiness tool has now been replaced by this platform.
