	What is quite ironic is that many operators now switched to charge rental fees for their under-powered, and not timely upgraded devices, rent that could easily be used to purchase far more capable devices (that would actually justify the rental fee).

	Well, the ingress traffic shaping definitely should be virtualized upstream of the actual CPE!

	But do we know whether mobile phone SOCs actually make good routers?
