I've made GUI Installer for Need For Speed Undercover. It will allow user to select .ipk file and gracefully install it into system(data files to /home/user/MyDocs/Games/NFS, binary and symlinks - /home/user/Games/NFS). It's available in Application Manager now(extras-devel) as nfsu-installer.

I'm going to make universal installer for all known-to-work-with-preenv games, but not so quickly. It's written in PyQt4, the sources are in svn, so you can contribute as well.
