Sorry for the long time without any updates, but it has taken time to get to a conclusion and it is hard to write this. We have been struggling to find ways to get forward, but all have ended at a brick wall. This has finally killed our motivation and we have taken some time off to find some renewed inspiration. This has been our pet project for 5 years and we have achieved quite a bit, but so many things need to be solved before we will be able to get to what we want. We have tried to rethink some of the key features and started from ground up and tried different approaches, but every effort to make something new has ended up being too difficult to implement or just failed. We have to realize that we're simply not clever enough to come up with any good solutions. The project will lie dormant until we hopefully some day come up with some new ideas on to how to solve some of the challenges.
