Folder redirections (aka offline folders)

All, I have an 10.5.4 server bound to an AD Server (2003 Server). Authentication and the reading of GPO's work great (thanks to this great site). I can't set up portable directories because that amount of network traffic is prohibited in the environment. I can't have the AD schema extended (though I have vehemently begged), so unc paths can't be set up. I read on this site that there is a folder redirection tool in that you can import in WGM preferences details. Using this tool, is it possible to set up a designated folder that will 1. Sync to a server for back up and 2. be able to be viewed offline. Is this possible? Any help would be greatly appreciated. Thanks, Dave
