The topic may have been ‘solved’, but I might draw your attention to this post, which I posted over three years ago SAFE Desktop App Tutorial. I too was trying to ‘do some proof of concept work’. That was over three years ago. Nothing fundamental seems to have changed since then. At the time, happybeing provided some useful advice. If he reads this, perhaps he would let mplorentz and myself know when we can start using the sytem. Three years time perhaps?
