You Can Have Group Policy Preferences Now!
I've been a'bloggin' on Group Policy Preferences here, here, and here. But what you may not realize is that you can begin using GPP's even today! To manage them you'll need a Server 2008 or Vista (with RSAT) instance somewhere in your environment.
What you'll also need are the Client-Side Extensions (CSE's) on all your desktops. Start getting these installed now, 'cause you're going to like your new powers!
Download the CSE's and get started at: http://support.microsoft.com/Default.aspx?kbid=943729
