Several people have talked about the nesting cup for a Nalgene, but still not having the flexibility of the nesting stove stand like a military canteen set up. I came across this thread some time ago and made one out of a coffee can. Makes a great stove stand and windscreen. Easily accomodates a Trangia stove or bring along some Esbit tabs. I keep the entire set up in an Outdoor Research bottle holder for a compact, go anywhere package.
