That’s great! The first client-only implementation will really start to move things to the next step. Is it going to be open source, or Google proprietary?
Open source. It has to be - I am developing it as a personal project in my spare time and Googles policy is that this is only allowed if you open source the results. But I would have done that anyway.
I managed to spend my first coins on the testnet with my app a few days ago, hopefully will get another chance to make progress this weekend. Probably will have something to show publically sometime in Feb, touch wood.
