Microsoft created quite a reputation for letting third-party developers build apps and then either purchasing the company or copying and driving out of business those that were most successful.
Skype has said they aren’t opening their network because their customers haven’t asked for it. Is that the truth, or is that just a convenient excuse?
If Gizmo5’s OpenSky proves there is a market for SIP to Skype, will Skype “cherry pick” that app and build that feature into their service? Or if Gizmo5 shows there is demand for it, perhaps they still won’t do it because maybe it’s not really about business – maybe it’s about religion, the church of Skype.
