This.
Though, I go the VIA route typically. Now that I've got a good grinder, I'll probably bring grounds with me now.
I've used the Jetboil in all kinds of conditions from -30F to 80F, and it's simple, fast, and cleans up easy. It's purpose-built to do one thing well - boil water, and it does so, quickly.

IMO the simplest, quickest, easiest cleanup and best combo for portable very good tasting coffee is:
* Jetboil for heating water (super fast, very efficient, compact and relatively affordable)
+
* Melitta coffee funnel with paper filter (cheap, small form factor for easy storage and clean/quick clean-up not using much if any water)
+
* Your favorite pre-ground coffee kept in a small sealed stainless steel container (here: http://www.noplastic.ca/stainless_steel_airtight_containers.shtml.)
Yes you could take a few more steps down and rely on concentrated coffee extract or Starbucks VIA...but the above isn't much more of a sacrifice in $ and inconvenience but the flavor difference in the cup is HUGE.
French press is great too but will require quite a bit more water for clean-up...
