I read this article in the IEEE spectrum magazine, and found it very interesting. I don't know if you already read about it or not, but if it is doable, it can change many things regarding perspective on, mainly, bandwidth, and other stuff.

I wanted to have the opinion of you guys who work in the networking/isp/internet department, where you have a lot of load on your network infrastructure.

Here's the article:

edit: By the way, the author is one of the inventor of the modern router/internet
Hardly revolutionary but he might have a good quality router.
as rolf said, it aint revolutionary, different vendors have diffrent methods of implementation. this is just another one, im more concerned with the fact that in what kind of backbond do you need to handle raw IP routing when nowadays there as so many underlaying protocols that voids such heavy requirements of handling all routing at the IP level. but yeah, there are certain cases where such is a requirement, but in those cases i would also consider QOS and dev null as well..
