Rumor has it -- as reported on Search Engine Land and Liveside -- that Microsoft is rebranding its search under the name kumo.com. According to the reports, kumo.com is owned by Microsoft and points to search.live.com nameservers. It also provides Microsoft employees with an internal site.
Whether or not it's true is only speculation at this point. However, sentiment is pretty heavily expressed against Microsoft taking this approach.
