@Mark – I for one would use it. It would serve to allow other trusted people to provide some closure to those that just plain don’t know if anything has happened.

So many of us now have relationships with people we have never met in the flesh, and likely never will. A plugin like this would be very handy.

Of course a good paper blog (a.k.a. moleskine) would likely contain similar details for the immediate family to know where/how to proceed as well.
