10 a.m. -- At Facebook .. Crammed full of reporters .. Waiting for announcement. Buzz is all about video chat.
Apparently Google+ Hangouts group video chat is such a "killer app" that sources say Facebook went into speedy negotiations with Skype to battle the competition. (Could it be because Mark Zuckerberg and his various Facebook colleagues noticed it after joining Google+ in droves?)
TechCrunch first put out the rumor last week, mentioning that Microsoft Corp. -- which is the pending owner of Skype -- is also a Facebook shareholder. So if Facebook were to use any kind of video chat service, wouldn't it make sense to use Skype? But now that Hangouts is being touted as the coup de grace of Google+, Facebook may have put the accelerator on the project, according to the New York Times.
Justin Uberti, Google's tech lead for real-time communications, explained on his blog that Hangouts will also be opened to third-party apps and services, something Skype is not. Another problem for Skype is that it's operating on older technology, according to the Business Insider.
Skype is built on peer-to-peer technology. Each Skype call is routed using directories stored on the PCs of other users, and the calls are connected directly from PC to PC. That works fine when you're connecting with one or two other people, and is a big reason why Skype . . . has been able to scale massively without a lot of expensive infrastructure.
The problem is that as Skype adds more people, the same peer-to-peer tech requires way more bandwidth just to maintain connections and slows down, one of the reasons it recommends video chat with no more than five people at a time. Hangouts is built on video streams routed through Google servers, more expensive but better for a larger-scale multiperson video chat.
So, if Facebook is launching video chat with Skype today, it should realize that its technology is already a little antiquated.
You can watch the announcement, live, right here. And NBC Bay Area Tech Reporter Scott Budman will be at Facebook HQ with live updates.
