Well, I thought so, but history proved me wrong. For those of us not in North America, the need is actually far greater on occasion. > Anyway. My point is that BGP is your friend.

Because the people doing one thing don't usually speak to people doing the other. Unless some behemothic (is that a word ?) company like Cisco (only as a bad example - they do hare some stuff) doesn't invent it's own protocol that is patentable, then there will be no standard to copy. Innovation in this arena is pretty much dead it seems. BTW I can actually see that the use of BGP for access control and logging application access would be the subject of a patent application by the greedy, I hope people can recall prior art in the future.
