A. RemoteFX is a new set of technologies that will be integrated into the Remote Desktop Protocol (RDP) to improve the remote end-user experience by building on the improvements Windows 7 and Windows Server 2008 R2 made related to bi-directional audio, Windows Media Player playback redirection to the client, and desktop composition (enabling remote Aero).
RemoteFX expands this rich end-user experience to other types of workloads, such as 3D applications, DirectX, WPF, Silverlight, and basically any media type, giving remote users an experience that's equivalent to local execution. The exact technologies to be included are still being finalized and could change up until release time. RemoteFX builds on technologies Microsoft got as part of the Calista Technologies acquisition.
RemoteFX will be available to users who connect to Server 2008 R2 SP1 Remote Desktop Services or Windows 7 SP1 virtual desktops using the SP1 Remote Desktop Connection client.
