I do appreciate that you're here and I know you have limited time.
I want to ask some specific questions. For me there's the Street View, street imaging, mapping, cartography, photographic process. There's the payload data download. There's also the collection of Wi-Fi hotspots. I think the commissioner is working on the payload data issue with Google now, but I'm concerned about the Wi-Fi hotspots. Folks from the commissioner's office did identify that there could be privacy concerns around that, and you've raised several things today that I want to ask you about.
You said that many companies have done the gathering of Wi-Fi hotspot data detection; they've done that process. It's not only Google. Do you know how many companies have done that?
