As such, I hereby imagine all of you - and yes, I know someone actually reads these damn things, because the view counter keeps ticking upwards - are hanging by a very thread, eagerly anticipating my words of algorithmic wisdom. Rest assured, I have not forgotten you - and wipe that drool off your chin.
Fact of the matter is, this thing just keeps getting cooler. My first stab at it was workable, but didn't really correctly solve nested pathfinding problems too well in highly dynamic cases; so I've reworked a few aspects, and ended up with an even more powerful arrangement. As soon as the kinks are ironed out and it passes unit tests again, I'll see about getting the code annotated and ready to post.
At the risk of inflating that overstuffed ego to the point of popping, I dare say this is some pretty darn nifty code, and its potential for doing cool things in solution-space searching gives me little shivery feelings up the spine.
