Is there a website or tool that can be used to easily determine all or
the majority of sites owned by a company?  For example,
Kraft(www.kraft.com) has many sites, some associated to its
brands(www.crystallight.com) and some associated with its
divisions(www.nabiscoworld.com).  While one can determine all of the
sites associated to a company through a manual searching process, I'm
interested in a tool that automates this process.
