I believe a third option also exists and has some but not so significant market share as the first two: DSL adapter resides in a PCI card or USB stick that's plugged to the computer.
As a result, 'no host changes' becomes more blurred and in practice, anything a DSL router needs to implement must be implemented in common host operating systems as well.
But I guess the perspective the DSL forum has here is that they can tell the user/ISP deploying this technology to buy a new CPE (brings in more money too, yay!) but they cannot require the user to upgrade their host operating system.
The trouble that I have with this is that the model where the modem is a gateway that actively does IP stuff is that it gets in the way of transparently passing IP to and from the network. I'm currently in the position to get a new (probably) DSL line and all services include a "router", which I take to be a NAT device. I really don't want NAT, but if I have to have it, I want this function to be implemented in a device of my choice rather than what my ISP could get on the cheap this month.
