I have been using http://neo-layout.org/ for years now and it works very well comes out of the box with Linux and does pretty much the same. If you type only in english you will be wasting a few keys because it has german umlauts but it is imho still nicer than qwerty.

At least with the windows AHK implementation you can also keep the qwerty layout and just use the two useful additional layers with the special characters and arrow+number keys.
