Google knows your MAC address

Interesting Telegraph report.

Every WiFi wireless router – the device that links most computer owners to the internet – in every home has been entered into a Google database.

The information was collected by radio aerials on their Street View cars, which have now photographed almost every home in the country.

Interesting. I wonder what would happen if I went about the streets running Macstumbler. How long would it be before Inspector Knacker began to take an interest in me? After all, he’s already obsessively interested in my street photography.
