I didn't really intend to start a discussion of whether the shipping ban was justified; the rules are what they are. My concern was whether there would come a day in the not too distant future when, as a practical matter, those lovely little canister stoves we've all come to know and love might be rendered obsolete by a lack of fuel.

You're right about alcohol being readily available; white gas doesn't appear to be a problem yet, either. Both are sold online, and stores have a ready supply of both. (Just out of curiousity, would a can of white gas or alcohol pose the same fire/explosion hazard if forcibly ruptured in machinery?)

And, who knows - maybe they'll figure out a way to re-use the cylinders, like we do our patio grill tanks. We'd end up buying an empty cylinder, and taking it to a local store to be filled and refilled. Jimshaw - you're an engineer - if you wanna get rich quick...
