throwawaywifi

They acknowledge but do not even address the "cops breaking down your door" problem. I don't think it admits of a solution. Technical approaches like putting unknown MACs behind a firewall to block filesharing or filter the web are imperfect and prove that you knew leaving your wifi open might help baby-rapers.

(Pardon the throwaway, but I do run an open wifi. If I do win that unlucky lottery, I don't want some zealous prosecutor digging up this comment.)
