From this story on scientificamerican.com:
_"...Such questions are set to be addressed March 15 at TEDx DeExtinction, a day-long event in Washington, D.C., organized by Stewart Brand's Revive & Restore project. Brand previewed the topics for discussion last week at the TED2013 conference in Long Beach, Calif. Scientists are actively working on methods and procedures for bringing extinct species back to life, says Ryan Phelan, executive director of Revive & Restore and co-organizer of the TEDx event.
__"The technology is moving fast. What Stewart and I are trying to do with this meeting is for the first time to allow the public to start thinking about this. We're going to hear from people who take it quite seriously. De-extinction is going to happen, and the questions are how does it get applied, when does it get used, what are the criteria which are going to be set?"_
