Well, there may be a way to make a PSK tin that actually works for boiling.
Take a Nalgene bottle cup. Stash your gear in that. Using a side cutting can opener, take the end of a coffee can- it fits great as a lid, at least Maxwell House does. Couple of big rubber bands to keep the lid down, and a quart freezer bag or two to keep it dry. Won't fit in the pants pocket, but a jacket pocket, sure.
