My knowledge on mobile device security is pretty limited.  I am just trying to wrap my head around the value of your 
passcode.  I suppose it would be good to know if I could get covert access to the device itself so I could see what is 
on it.  I would however have to get some malicious code on the device to get the passcode so it would seem to be easier 
to put malicious code on your device that sends me whatever I need the passcode to access in the first place.  I guess 
one of my thoughts on computer security in general is that if someone gets physical access to the device, it is 
history.  I would not count on the passcode to be very protective because it would seem that there would be some kind 
of way around it through the hardware vendor, maybe not but someone would have to convince me that a backdoor does not 
exist.

Kind of seems to me that if I am deep enough in your mobile device to 
get your accelerometer data, I probably can get access to your stored 
data in the device. The only reason I think I would want your passcode 
would be to physically steal your device and then try to use it.

This is one of those attacks that is probably possible but not 
practical. Interesting blog however.

I dunno, Steve; think "trojan horse".
