I don't see why you would say the 24oz can could not be a good pot. I've been using one as a pot slash water bottle for months now and love it! I've been using the same one the whole time and have had no issues with durability. Also have had great boil times with 2 cups of cold water. The diameter of the can is NOT the same as a 12oz standard can.
If you do a search for a Monster "BFC" can, you will find a 32oz can much wider than the standard 12oz can. I'm not sure if it is the 3.25" diameter that a Fosters can is, but it will swallow a standard can. The "BFC" may have been what Dale has seen.
