Having a solid use case or two is also helpful for those of us who
don't have a GTP/GPRS background.  I did spend some time reading a few
things on GTP, but I don't feel like I've made much of a dent on
understanding how it is actually used.

Harald, Pablo - I know you both suggested taking a slow iterative
approach to merging functionality, perhaps you could also help those
of us on the SELinux side better understand some of the common GTP use
cases?
