Good idea, if I am not online for while then something bad must have happened to me, probably was hit by a bus and passed away. Then this time capsule with my encrypted information that I want to pass to beneficiary could be very helpful.

I like inactivity based time capsules, good idea!!!!

yeah, I needed something like that, if I am inactive online for long period, then most likely I am dead and time capsule with all my encrypted credentials can be emailed to my loved ones.
