Why not a simple toggle to allow turning off to require a passcode. Even rebooting using the home and power button could be made set a flag in the phones storage so that any attempt to reload new firmware via itunes on the reboot would need the keycode to be entered via iTunes etc.
I would like to see Apple seriously look at this ease of loading firmware on a stolen phone and rendering it useable once again (Until the carrier blocks it, but thats usually for 1 carrier or 1 country - send it overseas and that is bypassed).
Already thought off that...
I agree, which is why I suggested iTunes could send out the location of the Device when it's plugged in. It's just an idea, personally I think anything that gives me a better chance of getting back my beloved iPad has got to be worth a shot.I kind of thought it should be optional so you could just turn it on in settings.

How would that help? Anyone savvy enough to perform the necessary steps to blank the phone isn't going to be connected to the internet while they're doing it. Find My iPhone/iPad/Mac works just fine how it is. If you want something more, look into Undercover, Prey Project, or any of the other apps that are branded as "theft recovery" assistants.
I thought you needed to have an Internet connection to restore, even if you use shift restore for pre-download software, iTunes refuses to restore software without checking it's ok with apples servers first.
