They call the cherries cascara, and I have come across them in some specialty coffee shops packaged just like the beans. You can pour hot (not boiling) water over them and prepare a tea-like infusion. It tastes sweet-ish without adding anything else. It gives a pretty noticeable kick to me when I drink it, even though I am a regular coffee drinker. I think it is worth a try, if you haven't done so yet.
