I've heard of some people using something called an elephant sock. Basically a garment large enough to fit both of your feet in. I guess my problem with something like a sleeping bag liner is that it is single-use and redundant. I imagine a a garment large enough to cover both feet could be made quite easily and weigh about as much as a poly t-shirt. At summitpost some people have reported being comfortable 30-40 degrees below their sleeping bag's rating wearing their insulating layers. I would think that the heat generated inside the sleeping bag would keep the temperature inside the bag at a nearly universal temp. Maybe your sleeping bag has cold spots near your feet. I've never had a problem with this. Your avatar is freaky looking by the way.

Not saying this method doesn't work; personally, I agree with it and I do it. But on one occasion, my feet were freezing in my sleeping bag so I put on two layers of socks (seemed intuitive). But I never got 'em warm all night long. After talking with a climbing partner the following morning, I went with his suggestion the next night: liner socks + sleeping bag liner + sleeping bag. My feet were warm that night.
Maybe it has something to do with trapped air / layers, and how "spacey" those layers are (i.e., if your "liner" is pressed against your body, like a sock, it's not going to trap warm air as much or as well?). I don't know. But based on this experience, I give liners props.
Quit whining and move your %$# up that mountain.
