You might want to look into a sneakernet by Avian Carrier; not
instantaneous by any means, but tremendous throughput can be achieved

"I always say to people, ‘No one earns $100 million. You steal $100 million.’
People earn $10 an hour. People earn $40,000 a year. ‘Earn’ means work. Okay?
It doesn’t mean steal, which with these vast amounts of money, of course you
steal them." — Fran Lebowitz
