The Live Search name looks to be nearing the end of its existence.  Barney Pell, the founder and CEO of Powerset who became a search strategist and evangelist for Microsoft post-acquisition, confirmed a pending change with a tweet this weekend.

Microsoft has plans to launch an experimental search site called Viveri sometime this summer, the company announced at its TechFest event.

Viveri will allow researchers to test new concepts and receive public feedback without having to add features to Live Search.
