Project Gizmo Challenges Skype
valmont writes "The Register is offering an interesting introduction to Project Gizmo, a new player in the Voice over IP field, poised to challenge Skype with its ability to interoperate with others thanks to the SIP protocol it complies to. Whereas Skype has selectively licensed usage of an API that offers limited insight into a closed protocol, a closed ecosystem solely controlled by one organization, the SIP protocol is open. Free open-source proxy/server implementations are sprouting up, and many developers are actively working on SIP clients. The Gizmo Project is the first to bring a truly-usable, user-friendly, cross-platform SIP client (Mac, Windows, Linux coming soon) to market. Meanwhile, theappleblog.com is already offering a Gizmo Project Wish-List to promote better interoperability between current and upcoming SIP providers, to make it more practical for users of disparate SIP clients to communicate with one another."
What about a BSD compatable client? Last I checked... there are no x86 voip clients that run on openbsd. Although, it is great to see them creating a cross platform client.
STUN helps - but only in about 80% - 90% of all cases. E.g. it won't be able to traverse symetrical firewalls. And even if you get the basic call setup right - try to transfer a call between different phones which are behind different NATs - and have fun! While some may argue that broken firewalls are the users fault, just see this from a users view: Skype works - always. SIP works - sometimes. Which one would you prefer?
Skype for all the gripe we may have against it for being closed source and not interoperable with other VOIP providers (FWD, Vonage etc..) does have the most important feature (and holds a monopoly for it too):Encryption
I didn't like having an old fart snooping on my AIM conversations a few years ago and I put an end to it very quick; I've been using Trillian and now Adium with secure IM and OTR encryption.
As much as I like having cheap calls and all I rather my private conversations stay.. well... private.
Skype is the only interplatform secure voice application.
Gizmo can take it's fancy gui and go right back to the drawing board as far as I'm concerned.
If you ask me voip with sip (ala vonage) is just a disaster waiting to happen, sooner or later somebody will write an article in NYTimes or some mass distribution newspaper about how insecure and easy it is for somebody on your campus/office/wifi... LAN to record your conversation and everybody is going to freak out.
Encryption should be built-in NOW before it is too late to change the standards.
Artificial intelligence is no match for natural stupidity
