One similar technique was we basically created our own fake ISPs, disguised as rural wireless Internet providers. Paid yearly ARIN fees, had or own /20 blocks of IP space allocated, etc. We specifically requested ip filtering completely removed from our peering connection with major upstream/backbone ISPs. They did so without question. This allowed us to source route any IP out to the Internet. Then, we would purchase large blocks of IPs (a couple of /20s a month) from Romania and Argentina. We would create GRE tunnels over to RO and route them back to the US. It's been years since I was involved so my memory of the technical details is hazy now...
