Diet, NVDave has made a lot of noise about security.   I sort of think that I have more important things to worry about when there are at most a handfull of computors which have a half a chance of physically being able to reach my access point, and virtually all of those belong to people who could walk into my house without knocking and not cause any alarm. 

What is your take on the issue,in real world, "edge of the earth" terms?
