MathDrag'n

Woo-hoo!  (Slaps self on back, high-fives internet in general!)  Well, I think I've officially got it working.  I finally ran MathDrag'n on a Mac and got it to automatically connect with Mathematica!  There were exactly two typos in the entire program that were causing the connecting code to fail catastrophically, both of them a single wrong character in just the wrong spot.  Amazing, really, how stupid computers are after all the work we've put into them.  All the behavior seemed to be exactly what I had come to know and love from my PC testing, so it seems likely to have worked well.  (Ironically, I think I discovered a bug in the more general Java code that I may need to track down, all while having debugged it on a Mac.  I'm going to do that at home  until I have CVS or something similar set up.)

It also reminded me just how much difference a good debugger makes.  It took an estimated five minutes to track them down with the debugger.  The basic logic was rock-solid; I had really done my research before-hand, and it was time well-spent, but I still couldn't follow the code with my eye well enough to see the tiny little mistakes.  Ah well, it's done now.  YES!
