Article didn't mention it, but Justin's blog post did:

"Standards-based: XMPP, Jingle, RTP"...

We're working on publishing the spec, which should be available soon. In fact, it's already implemented in libjingle:

http://code.google.com/p/libjingle

Could you link us? If they're opening up the technology behind it, it really will be amazing.

I have to wonder if it's based on Muji or if it was built from scratch.

EDIT: Never mind, found it in the article. http://juberti.blogspot.com/2011/06/announcing-google-hangou...

EDIT 2: Oh, you're a Googler. Good to see that you'll be opening it up. :D

Very excited to see this used here and know that it will be replaced by even more plugin-less awesome- WebRTC.

I wonder if that's just a Google-internal thing or if Google+ will embrace other social networks wanting to integrate.

HN Feature Request: a filter that strips the word "amazing" out of all headlines.

Sounds interesting and all, but how is this "amazing"?

P2P can introduce latency

Can someone explain this to me? I guess if your video has to go via multiple hops, that would be laggy, but if you connect directly to each peer in the conversation surely that would be less laggy than a client-server architecture?

It's because of limited upload bandwidth when sending multiple copies of a stream.

I think "the hint" of the amazing technology behind Google+ Hangouts would be more appropriate.

Could one of the people involved please publish a more detailed blog posts as how all these pieces are linked together. The tweaker in me wants to start fiddling with it ASAP:

Fully browser-based/cloud-based

Client-server: leverages the power of Google's infrastructure

Designed for low latency (< 100 ms) and high performance (multicore + hardware acceleration)

Standards-based: XMPP, Jingle, RTP, ICE, STUN, SRTP

Fully encrypted (HTTPS + SRTP)

"WebRTC is supported by Mozilla and Opera" -- hmm, someone is absent from that list

Actually, to be fair, Microsoft isn't the only one missing.

Chome is moments away from getting this it seems:

Great blog btw, I check it each week to see what's cooking under the hood of Chrome :-)

Awesome? Umm it doesn't work on my Google supplied Cr-48.

Worked on my Samsung Series 5, but when trying to do a youtube watch with a friend and the tab crashed.

Yeah I'm dumb and I had the "Click to play" flag turned on so it was blocking it.

Hopefully will when the plugin is baked into an update.

Flash has had peer-to-peer video support for 3 years now and it's available to 90%+ users on the web. Chatroulette was built in 2 days around this technology. Whenever "standards" catch up to Flash, it's being touted as "amazing".

The article clearly states that whats interesting is the client-server infrastructure behind it and the fact that it isn't P2P.
