Yesterday I was with a customer and we were talking about using Rights Management Protection with RMS and Windows 2008. As part of the eCAL Suite licensing package our customers have the client rights to deploy an RMS Server and provide protection for Outlook messages so with a campus agreement (with eCAL Suite) and a Windows 2008 Server license you can protect email with RMS.
For information on how to deploy RMS with Windows 2008 please view this video: http://www.microsoft.com/winme/0706/29882/ADD-401_demo1/f.htm
