David has a blog post on "From Virtual Personas to a Digital Afterlife" on the blog of the new Aura website/service- "designed to help you prepare your memories, important information and connect with loved ones before you die", part of the burgeoning digital afterlife/memorial sector but also looking to open up the conversations ahead of time.

It's also interesting to compare some of the ideas in the post with Channel 4's recent documentary on Peter: The Human Cyborg as there certainly seems to be some common ground worth exploring.
