But I did screw up on my last trip a few weeks ago - had no way to do some fresh coffee.  That was a disaster!  I need a some sort of compact coffee brewing system.  That is a MUST.

A cup, hot water, and ground coffee will get it done. Nice if you can filter/strain the grounds, but not strictly necessary---just don't drink it to the bottom and swallow the grounds. 
Ground coffee in hot water is the way we make coffee in our "french press" coffee maker: I prefer it. 
Maybe I got used to dumping coffee into the hot water from my old Army field days. . .
