Hi @scottm,
We’ve been thinking about digital ownership and security of connected devices a lot in the last year, and we’ve been working out a more flexible, smoother claim process for physical things that change hands.
For example, if someone buys / resells their internet-connected <insert cool thing here>, the previous owner shouldn’t be able to hold it ransom, but at the same time you don’t want someone taking over the locks on your house without your permission.
We built a lot of this already, and I believe we’re intending to include this with the Photon, so for example you can operate it in ‘shared mode’, or a ‘locked mode’, which will make it very easy to transfer ownership in exactly this scenario. 
Thanks,
David
