Due to numerous problems with the service and unfortunate marketing choices, Skype has an uncomfortable week in the spotlight. The Skype gripes began last week with Aswath's scathing rebuke of the new Netgear Skype phone:

Netgear router can help assist the Skype client in NAT/FW traversal. This means that the supernodes do not have to do STUN and TURN functions, minimizing the resource requirements on the supernodes. The router can give priority to Skype traffic as the packets go on the broadband link. This is all well and good. But this also makes it easy for a Skype client behind a NAT/FW to act as a supernode.

And, right after that, Om pointed us to Paul Kedrosky's Supernode experience:

While travelling I was alerted that my main office PC was sending out enormous amounts of traffic. According to the tech person involved, the culprit was ... Skype. As Bizarre as it might seem, the contention seems to be that my PC became a sort of Skype super-supernode, one that was routing all Skype traffic for, you know, the world, and that was causing unfortunate issues, like saturating a centi-megabyte pipe.

Now, add to that Skype's issues with third-party developers and they have quite a PR mess on their hands. Since you won't experience the supernode issues with Gizmo, what's stopping people from going with Gizmo's SIP open application?
