User settings and perferences with App Attach

When I create a package of an app like Adobe Reader, I add the PSF with MfrFixup to the package.  This will redirect those changes to the user local profile %localappdata%\packages\{PackageFullName}\Localcache area.  In an AVD environment I would then use FsLogix to redirect for roaming purposes.  You can either have a general rule to redirec all of %localappdata%\packages (and eat up a lot of disk) or make specific app package rules for the files you need.  For most all that is the registry.dat file and a single configuration file for the app.
