A general statement:
"When people buy a toaster, they know it's probably not going to blow up when they plug it in. But when they buy a consumer device like the Nike+iPod kit, they have no idea whether the device might enable someone to violate their privacy. We need to change that."
from a very specific article about the fact that the Nike+iPod device broadcasts an unencrypted signal readable in a 60 foot radius. Brilliant. :)
Anyways, I am looking for any signs of "cracks on the smooth edges" of the end-to-end controlled "solution" that is the Nike+iPod offering, that would potentially allow the coupling of GPS data somewhere along the process, preferably during the activity being captured, i.e. running or general out-and-aboot-ness.
