BURRO This could be a sweet little tool. I appreciate the effort. It is clear a lot of thoughtful work has gone into it.
That said, I tried it on three one-page PDFs and it failed on each. (iMac, Intel Core 2 Duo, 2.16GHz, 1Gb RAM, OS v10.4.10).
Also, unless I *really* lack imagination about the precision that this kind of tool can accomplish, and its potential applications, I would encourage the authors to look at the idea of an end-product that could be priced in the $10-30 range. Perhaps at that mark, enough units could be sold to get close to the profitability of selling just a few to power users at $250.
