I met couple of people studying piano performance rules and applying them to the synthesis of piano performances. There is a group at KTH Stockholm (Royal Technical University) lead by Prof. Johan Sundberg who did a lot of work formulating performance rules. They implemented a rule-based system for playing contemporary piano pieces by a computer. Their work has been published (among other places) in the Computer Music Journal (I'm not sure about the number, but should be around 1991-92, I can check it at home). There is also a guy called Roberto Bresin from Italy who implemented their rule system using a neural net approach. His goal was to teach the network to adapt to a specific player's style. This is something that may be needed in our case. I met Roberto a couple of times at various conferences, and I heard his demos. Well, the problem seems to be quite difficult, so don't expect a ready-made, fully working solution.
Btw., several sequencers have a 'humanize' feature. I don't know how good or bad these are, but certainly they try to imitate the human player somehow.
I will collect the references I have and post them later to the list.
Back to the WAV to MIDI conversion, I'm very much interested in this thread as well. I found the GA idea quite interesting. Let's keep talk about it!
