I was reading this article: Should Apple Acquire Skype?
and Ted Wallingford offered some interesting analysis.
He talks about the problems of scalability in Skype (namely the directory search) and how Apple's iChat should be able to "take on" Skype.
He also offers some interesting ways for Apple to get into the VoIP game, such as buying 8X8 Networks, the ones behind the Packet8 voice over IP service.
