Or put a heat and radiation resistant usb-drive in a capsule (complete with small parachute) loaded on a sling shot directed at Earth. Would certainly take a long time but would be fun.

Seriously though: what about launching a rocket in the direction of the outer solar system that launches mini relay satellites that act as a mesh network? Put a few bigger ones in the asteroid belt and the rest in various Lagrange points around Mars, Jupiter, Saturn etc.

Path loss, Shannon limit. Until we figure out how to build 150 meter parabolic dishes in orbit, or on the moon to supplant the NASA deep space network.
