Interesting report on how Microsoft phases out products

Today I had an architectural discussion with a colleague on the possible approaches to build applications on top of the Office platform. He mentioned the Information Bridge Framework. I had some reservations since that technology never really seems to catch much attention nor concrete applications, and therefore being doubtful on the future status of it. I did a quick search on the net for recent IBF news to check it's status and liveleness. The result was a confirmation in my doubts: Microsoft already in 2007 declared the outphasing of IBF in favor of VSTO...; within this report (Directions on Microsoft) there is background information on what grounds Microsoft decides to outphase products and technologies.
