If I was you boys I would now sit down and try to bring @Traumflug onboard and three of you get on the task to make a clear roadmap for this project because as of now you're the glue holding it together.
If @Traumflug is gone nothing good shall come to this idea. Please bury the hatchet and bring your best ideas to the table making sure you are honest about your intentions but also make sure that the other two are happy with the way ahead. The future of many of our shops depends of you three guys and I'm sorry but if you had worked so hard for this idea for so long time I believe that funding will have to wait.
If you really bring the proj back on track (with clear and user-oriented roadmap, clear and open communication with us, timely bugfixes and code maintenance) I believe that the investment of money and time you made will pay back. And then you will have the community behind you as it was behind the founding members.
If now the proj get a forge it's all gone - the money to be/have been invested, your time and energy. Forget about our shops, fuck it, the people that make money will migrate, the ones like me that do it like a hobby will simply close down when time comes.
The idea of better, open source, working and user-oriented ecommerce platform will be gone...
