As for the trust issues, you can easily just say "look under the porch in my house", you don't have to reveal all the information there. Or, just encrypt things.
Nice. Do you actually make a reasonable amount of money the on service? The reason I ask is because these dollar/lifetime web services are popping up more, and I find it to be an interesting pricing model
Not overly, but it's just a side project for me. I should start marketing it more, I chose the lifetime pricing model because downgrading someone's account if they died didn't really make sense for the project...
I'd definitely be up for it if IFTTT were. Do you mean as a "switch triggered" thing, for Twitter, Facebook, etc?
A problem with that is that people can have custom intervals per-message, so they can have one for "I'm missing for a day", one for a month, etc, so there's no "one" switch. I could make one, though, I guess.
