First up, yes, we are going to OS all the code and have been talking with Richard Stallman himself about which is the right licence (yes, really - you should have seen the response when he emailed us. I stopped dead in the street and shouted "Oh my god!" to the bemusement of passers by when the email popped up on my phone).

This project has come about at great speed, none of us has slept much in weeks, there are many, many things we need to do - we're not hiding the source because we're evil, we just haven't had a minute to put it up on git or whatever public svn system we decide to go with. Please be patient with us :)

More answers to follow as I read through the comments below.
