Oh... pity. Still, maybe he did (or would) make his code available. If not, what he did is still a good #todo list. I wish I could help with something myself, but it will take quite a lot of time before I actually learn anything (though I am trying to understand how stuff works). Someday perhaps.
Edit: Just read a post by Lord Tirian further in the thread linked by whoward saying that the code is available somewhere.
I'll post a bit more later, but in short The Smart AI dll changes are already in WHoward's DLL. They'll be folded into this. I'm looking at his changed before I do my own. also, all the new building/yields/changes are purely 'proofs of concept.' I'm not one of those modders that is personally attached to his changes. You don't like a change? We fix.
Consider it a 'starting point for debate.'
