Yes! I didn't mention, but I contacted all contributors directly over the last month or so and asked for permission to re-license their code. We only went ahead with the change when everybody had signed off on the shift. In fact, all the contributors were postively disposed to the shift (with a few even suggesting that we go 'server side' immediatly to stop the AWS threat!)
