I'd say that argues for using the ol' Nalgene etc. only as a foot-warmer, and drinking out of the metal bottle?

  Ideally yes but it's really hard to find fully metal driking bottles. If you buy something like a Sigg aluminium bottle or no-name copy it will be lined with some kind of plastic. If you use a light weight drinking bladder that will be plastic too. I've read that risk is much higher if you apply heat to a plastic container. This is why you should avoid microwaving in plastic containers. So that leaves you either only using a cold liquids in plastic and accepting some risk or buying expensive (and relatively heavy) titanium drinking bottles.

      Just looked them up. Looks really nice. Maybe a bit heavy for me when hiking but really nice for day to day stuff. I like the Vargo stuff. Also the new Keego flexible bottles look really interesting.

      Using an insulated bottle kind of defeats the purpose which is to transfer heat from the water to yourself. You'll wake up in the morning with a bottle full of hot water but you'll still be cold.

        Kleen Kanteen sells non-insulated metal bottles as well; I've used them for this purpose (not sleeping, but holding against my body to help stay warm in a cool room). Bonus: once the temperature drops far enough you can also drink it for a quick internal thermal boost, if needed.
