FWIW, all those nifty no-pot snow-melting techniques are great to know how to use if you ever really need them, but the meltwater smell and taste would gag a maggot most of the time. Rancid woodsmoke smell and taste... I speak only from my first-hand experiences teaching all that sort of stuff in Alaska. Even with a pot, unless you have (and use) a good-fitting lid, using an open fire results in water that certainly is "flavorful" to some degree (most of the time). OTOH, it sure beats getting dehydrated if there are no other options.
