Who know what other "features" the enterprise edition supports. So i guess you find yourself in a bit of a sticky situation here. You could write policy for your enterprise edition yourself. After all Selinux is a framework that allows you to do so, but you will have to know a bit about the matter to be able to implement it, just like one needs to know a bit about netfilter and iptables to open or forward some network port. I want to help you implement a policy but it isnt easy for me either as i havent much experience with ruby on rails and its files.
