Hi,
I unfortunately don't have much expertises in this area, although I do have a few app developer friends. It would be interesting to see where this goes. No doubt the hardest part will be addressing the backend code, and allowing the app to compress data - after all, it needs to hold an entire blockchain!
Everyone else, here is the current status of my Gtk mockup for the new client. I've built 0% of the backend, and as of yet I don't plan to. At the moment, it's just something to get ideas flowing.
Enjoy!
