Thanks Awakening for the time zone ref.
It might be more practical to do this in waves. Similar to what they do for the World Tai Ji and Qigone day. It is a staggered ripple effect that sweeps the world at 10 am across the world. So a variation on this would be we all get together at agreed upon times for our specific time zone. The effect would be almost like a continuous healing time of focused attention.
