Just like with everything else. Someone somewhere will disobey the general rule. As moores law stays true, technology will continue to upgrade until it becomes itself an entity no different or better then humans.

The data will be wrapped, packaged, and transported so well that Cisco's bullshit wouldn't know what was coming through the pipe. With the generation of IPV6 addresses, and completely distributed & decentralized network architectures, as well as mobile web-servers, there is absolutely NO way it will stop.

EVER.
