As for your immediate need... might I suggest cowboy coffee...
a bit gritty.. but it beats chewing on coffee beans for your morning caffeine fix.

Heh. If you have some chocolate chips, you can chew them with the beans. It's a mocha!

In a pinch, though, you can stick a filter in a funnel, stick the funnel on a big cup, and pour some boiling water in. If wanna be a crusty punk you can use a sock.
