Skype has relationships with a large number of unified communications and video companies with solid channel presences, not least of them Avaya, with whom Skype partnered on a two-phase integration starting last September. How will Microsoft look to limit or change those relationships? It'll be easier than others in some cases: LifeSize Communications, for example, has Skype video calling integrated into Passport, its portable telepresence system, and LifeSize is also interoperable with Microsoft Lync. And Avaya does integrate its communications solutions with Microsoft's desktop and business applications just fine. But it stands to reason a few existing Skype relationships will change.
