I've been traveling stoveless for well over a decade, but the buzz I hear on the trails is that the canisters are very easy to resupply these days and are getting increasingly popular.
I second the pepsi can alky stove idea, as long as you're not cooking for a large group or using it to melt snow. If you cook more than one meal per day, alcohol may not be the best fuel in terms of calorie density.
Ah yes, the "Whisperlite"--neither of which is true.
