Ballmer "it would make sense for Lync to be called Skype or Skype Pro"
I found this nugget in an interview from last year: http://www.youtube.com/watch?v=ymdFBGiYr7c
basically he says that one name would make sense to encompass the communications apps they have. Lync is a professional messenger, so "Skype Pro" would be a good name for Consumerization. http://en.wikipedia.org/wiki/Consumerization
