From my experience Its not you who needs to hide, its the person who hijacks your wireless connections then downloads illegal content or commits an illegal act (usually hacking/ attacks). They need to hide and do it at the cost of an insecure wireless network.
Recent copyright and peer 2 peer convictions have highlighted the problem above, they trace offenders through IP address's then prosecute. Their computer is checked and they have no trace of the illegal download on the hard drive.
A common problem is people who leave their wireless network on 24 / 7, when not in use switch it off, then the hacker will use another network. All in my humble opinion.
