What Skype is trying to achieve by purchasing Gizmo sounds a bit complicated, and it will be interesting to see how all of this plays out. I've seen Gizmo referred to by other sources as a "partially scaled SIP P2P VoIP." Regardless, the combination of Skype and Gizmo still requires a lot of underlying software support (in Gizmo's case, Adobe Flash), and users will still need to download software to support SIP/P2P communications.


I should clarify. VoIP is peer to peer in the sense that it is routed, like all IP traffic. However, most providers use their own network rather than an ad hoc network where the peers are users. The latter is what Skype does, but not what, say, Vonage does.


I assume you mean for Gizmo. For most VoIP services, that is not the case.

The media path is P2P


Andy, if I'm not mistaken, most VoIP is not P2P at all -- that's part of what makes Skype different. I don't think Skype will be able to quickly port an SIP application to its P2P network, but I could be mistaken. Regardless, I believe they have a tall order ahead of them.
