Hmm, I think its about scope, if you pretend to be another company or announce their space its hijacking, if you dont accept routes internally or modify routes internally then its not hijacking.

Transparent caching has done this for a long time, the difference is it only works on traffic passing through the adjacent router, with this you can pull traffic from all over your network back to a single cache Steve
