I was hoping you'd be at least the slightest bit more specific :) are you working in a proprietary startup? are you working in academia? presumably you're working on a codebase with the intent to distribute it to users at some point?
I can't be yet, unfortunately. But there are definitely several different groups of very talented people working on this problem (think MIT and Harvard PhDs). I suspect some very interesting work will come out in the next year or two. Whether they are open source remains another question.
