A topic that is gaining attention : electronic property rights.
You buy an eBook (or at least the license) and you die. Do your heirs have the right to access that book? Ditto for music and videos from places like iTunes etc.
And say that you store your family photos on line (e.g. Photobucket or DropBox) rather than a hard drive or prints in a shoe box. After you die, do they essentially evaporate into cyberspace or can your heirs control these?
A lawyer’s wet dream !
Regardless of whether your family can "inherit" access to your digital content, it's disturbing that they can remotely wipe your device while the device is in your possession. That smacks of a warrant-less seizure of stuff in your possession.
I'm currently setting up a computer and access for a relative who is late in joining the technology curve. I highly recommend backups that are kept in your possession at home. Don't just rely on backups in the "cloud". If my devices get wiped, I simply restore from personal backups. You can also reset computer dates to dates valid within a licensing range for content. Lots of ways around these limiters on your accessing stuff you paid for - but you need to be proactive.
