Nuvio's ( http://www.nuvio.com) residential service includes an adapter with QoS and NAT built in. In theory you 'plug it in and go.' PPPoE connections being an exception of course. They are also introducing Bring Your Own Device so you can use something other than their Motorola VT1005S adapters (I believe vonage uses these as well)

Setup cost was like $40.00 for a "router with QOS". If you sign up, say I refereed you, I think I think we each get a free month. Number to use is 816 875 4282 if you do.
