Just got this working in Linux using the latest Cura and CuraEngine heads and I have to say it is amazing! It's fast and simple to use, and best of all the print quality beats the old Skeinforge backend.
One of my biggest problems with the old slicer was the old holes coming out to small and having to fudge models to the right size: http://hydraraptor.blogspot.co.uk/2011/02/polyholes.html
I did a print just now with a 5mm diameter circular hole and it came out at 4.5mm. This is a lot better than Skeinforge and the remaining difference may just mean that I need to tweak my machine better.
