that would be a lot of code to write...
I think we will get it one day but I wouldnt wait for it.
Well I guess the difficult part would be coding the 'randomisation' of the pieces at the beginning; other than that the rules are exactly the same. That said, there's an open source java implementation of Boedlander's method of randomising the initial position within the constraints of the rules (that castling is possible and that the bishops are on different colours) here:

So I don't think it would be all that difficult for someone who knows what they're doing to put into practise here.
Is there in the feauture going to be Chess960? I think that would be very good and fun! It brings more variety to this website, and more people will join.
