Aren't the metal water bottles you find in most sporting goods stores lined with something? Seems like the interrior are lined to prevent rust and corrosion. Wouldn't those liners breakdown and get into the water you are trying to boil?
Yes Most metal bottles have a liner sprayed into them. I do not know about popular brands such as kleen canteen. And yes they will melt off and break down into what you are drinking if heated in a fire.
That is what I have always thought. I'm just trying to figure out why so may on the forum are switching to metal bottles for their "dual" purpose to be able to boil water in. Maybe they just haven't thought this thru?

Guyot designs (also sold under the Nalgene brand) and Kleen Kanteen are both un-lined steel bottles. You just have to make sure to stick to the single-walled variety if you want to boil water in them. They also sell insulated (double-wall) bottles, but these are not safe for boiling water over a fire.

I've never tried it, but everything I've read on the matter says it isn't safe. Apparently the pressure created can potentially blow out a weakened area (like the welded seam) of the bottle like a bomb.
