"Proxies were originally what I used, but those are only so good," Dane said, looking thoughtful. "They just traced the routing of the data through the various proxies. Takes time, but it works. So, I have a better idea," he grinned. "We'd need a laptop, a spare wifi card, and access to a public wifi port. Once the deed's done we remove the card and trash it and then head home. As the wifi place would be public we'd be using a rather anonymous IP - it'd be akin to using a PO box instead of your home address when being mailed stuff - and if we destroy the card after we're through with it, it's MAC address is also lost and thus the whole thing is untraceable."
