OK I would be very happy to look at it so I can learn a bit about the hands-on and general approach here. Just send it to this address directly and I will look!
My interest is mainly to see this progress so any way I can help or tinker I'm happy to do. You can just incorporate my contributions if any, I don't care much about code authorship and such things, it just makes things more complex.

I'm going for vacation the next 2 weeks or so, but then it'd be great if we can start looking at this in-depth!
