Yah, it's a great paper. Nice quickie analysis Nick, but I'm sure that you know that the % you're projecting with planets is well understated because so far mostly only the quickie orbits are listed in the data you cited. We still have no clue as to what % of stars have close in (much closer than Mercury) vs further out (like our sun) planetary systems. Most of the further outs (if any!!!) were not yet 'detected' in that brief data set. Over time COROT and Kelper may answer many of those questions.

I think one reason the paper was published was so that the COROT team would have first dibs on any transiting planets in that data field. Don't want ground astronomers scooping them with discovery papers. Heh.
