Honestly I thought this was going to be about the problems of fully utilizing SELinux. There are bits of SELinux which are just missing - like a shared network policy server, or the various concepts of transiting SELinux contexts across things like network links to provide network-wide security. SELinux is one of those things that makes total sense to me, but the implementation just leaves so much to be desired - i.e. basically no practical usages of "users" in an SELinux context even though the concept is there.
