That's exactly what I thought. The title made me think this was an open-sourced Skype alternative, using the name "Skype" just to describe an analogy, not name the product. While this doesn't make any attempt to emulate Skype's functionality, it does use the name. Skype could argue that their brand would be falsely associated with this project. The name definitely needs to be changed.
