What about one of those mini wood burning stoves?

I've tried this with the firebox nano . Mine is the first generation and works fantastic. The only issue (not a design flaw) is that the stove will get filthy with soot and ash if you're burning a wood fire. That was enough to turn me off.
I would save a bit of money AND weight by rigging your pot with some picture wire so it can hang above a small fire like this:

Hope this helps. Cheers!
