we now have a test project ID , the builds are fine now, so ok to close ?

Well, I thought about making build independent of external Ethereum network. One of the issues with current test implementation is that test cannot be executed offline. Separating authentication and getting current Ethereum block logic can improve performance. For example if CurrentBlock is called few times during short time period it could cache and return same value without getting it from Ethereum network twice. But it is a subject for another issue I believe.
