The Google connection is interesting. Because Bitcoin's greatest weakness is that the integrity of the system can be subverted by a malevolent participant who has enough computing nodes to make up the majority of computing power. Not that I'm saying Google would do this. Or that Google couldn't do this if they just used the main C++ implementation. It was just an interesting coincidence because when one thinks of entities that might have massive computing power at their disposal, things like various major national governments (the US NSA, China, etc.), or companies like Google and Amazon, come to mind.
