So other than some "maybes", no one has seemed that interested or contacted me with anything serious. In the meantime I think I am close to solving this myself so I am taking down the task.
If you were working on this despite not telling me clearly, as I instructed, we can talk about a smaller compensation for your work if you have something to show.
@Dare
I read your last post as "you not having time", let me know if that's wrong.
You read it right. I wish I could help, but I took on too many projects this year and I can't really start anything else until 2014.
Bitcoin cards are a good idea though, and I hope you succeed. If you haven't gotten it working by next year, for whatever reason, shoot me a PM and I'd be happy to help.
