Coffee grounds are most effective when applied directly to the soil as a light (1/4 to 1/2 inch) top-dressing; they loose much of their nitrogen (the fertilizing stuff) within the first couple of weeks. There's certainly no harm in composting them, but they're most effective straight.
If you know someone local with a pine tree, fallen pine needles are a very good mulch for acid-loving plants. They slowly add to the acidity of the soil, which you'll need to do for acidophylic plants grown around here. Even if you plant the thing in a pot of perfect pH soil, over time the alkaline nature of our tap water will shift the pH of the soil. The pine needles will help counteract this, and tend to be much cheaper and easier than irrigating with specially treated water.
Noted. Thanks for the tip! I don't think I'm going to be hurting for coffee grounds any time soon, though, I think I can get a good two CF a week of the things at work :) I need to take that trip to the pine forest n of here sometime, and just get bins of the things...
