If you intend a 72hour BoB this could be an option.
It's small and cheap and simple enough to have them all over the place so that you will always have one pocketed.
My first thought when I saw the article was BoB.
I do a similar thing but with tea lights, slightly wittled down and a single layer of corrugated card wrapped around the outside and put back into the little case. Very smokey and sooty though but quick, easy and very cheap. a slightly more sophisticated and slightly cleaner burning version is to score 4 grooves up the sides make a cross of 2 longer bits of corrugated card ( long enough to wrap underneath the tealight and up the sides plus 5mm ) giving a tealight with essentially 5 wicks.
For a BoB stove the Swiss Army Volcano plus some tealight burners or hexi blocks and mini pop can alcohol stove ( to use fill mini alcohol stove, hold it level between finger and thumb, hold volcano stove horizontal, insert ministove into hole and turn volcano stove vertical, chuck a little extra meths into bottom of volcano stove which really helps prime and light at egde of gap ) will cover most bases including twigs and pine cones.
To make it even more flexible ( which I might do later today ) take one of the multifuel ebay stoves Rik_UK3 introduced us to
http://www.bushcraftuk.com/forum/showthread.php?t=28765 and the top from a glass jar. Remove multi burner from stand ( one nut ) drill hole through middle of jar top, place burner ontop of lid with bolt end through hole and put the nut back on. The whoile assembly can be dropped down the center of the volcano stove. This should come close to Jetboil/ETA Express levels of speed and efficiancy though I'd be little worried about prolonged use as the Volcano is only aluminium.
What you can end up with is a simple stove combination that is truly multifuel, wood, meths, hexi, gas, petrol and (if memory serves) parrafin. What more could you want from a BoB stove
[Update] Well that took a whole 3 minutes, used the top from a jar of pickled eggs approx 73mm diameter, fits down the Volcano with only a little fiddling but any bigger might be a problem, made the hole with a braddle and srewdriver while the cordless drill was recharging
If I can find some gas I'll do a speed test outdoors later.
[Update 2] I abandoned doing the speed boil test, after only 30 seconds, with the gas burner metal ( presumably steel ) glowing red about an inch away from the aliminium of the Volcano stove I figured caution was in order, hardly being set up to deal with if the aluminium casing melted, as the water may have then spilt onto it too.
