I'm not familiar with it, but take a look at this website http://www.hobbithouseinc.com/personal/woodpics/coffee%20tree.htm

. The pictures show a variety of colors, some almost look like a cross between oak and canarywood, or some almost between oak and walnut. The postings seem to indicate that it's pretty hard, so make sure your tools are sharp.
All in all, it looks like you may have a good find - but it depends on the color(s) you're looking for in the wood. Perhaps pick up a few feet, play with it, and try various finishes. Personally, I'm fond of General Finishes Arm-R-Seal. That's what I used on the cherry/walnut dining table for the 4107, and on the maple/walnut church podium I built last year. I normally use it over a coat of blond shellac on lighter woods (such as maple), orange shellac over walnut.
