I'm out hiking to enjoy the trip, not have some masochistic punishment drill. I drink my coffee sweet and Via works for me. All you need is a small titanium cup, an Esbit wing stove and some aluminum foil for hot meals. You don't need bring water to a full boil for instant coffee, oatmeal, or dried soups, it just needs to be hot. I have an Evernew 450ml cup with a fixed handle and the wing stove, aluminum foil and a folding spork fit inside with ease. If I really want to be extravagant, I bring a Ti Sierra cup so I can have a bowl and a cup at the same time. I'm sure there are many recycled plastic containers that would fill the same niche. My point is that it doesn't take much to have a hot drink or instant meal.
The idea of eating instant coffee or taking pills instead of having real meals misses the mark of being outdoors and enjoying life. I'm outdoors to get away from the sicknesses of modern life, not take them with me or even accelerate them. Sloooow down and savor your time in nature! Turn off the cellular phone and iPod, put your feet up and have a nice cuppa as you watch the sunrise. Feel the wind on you skin, hear the birds sing and the stream running, smell the evergreens, be alive :)
