More than it costs to have a chain of proxies in different jurisdictions.

Do like the Brazilians or Puerto Ricans did and hijack an old unused US military satellite.

Won't help you since anyone with an antenna could receive your satellite's signal, and the government's got some big antennae. Also, your ping times will suck.

Probably more then it would take to have it taken down by a missile, or be made ineffective by "interference"
