After live-streaming U2 concerts, Indian cricket and even Tiger Woods' confession, it looks like YouTube might be close to opening up live-streaming for all. Screenshots of a new YouTube toolbar with 'Live Stream' added suggest so, anyway.
TechCrunch spotted the toolbar addition on a YouTube employee's help page, so it's possible this employee uses it when enabling streaming for CitizenTube events, such as Tiger Woods' apology to his fans earlier this year, for his extra-marital naughtiness.
While of course there'd be massive problems with copyright and bandwidth issues if YouTube ever opened up full live-streaming for everyone, it's been rumored for so long now that it'd be crazy if they withheld the functionality to actually push this through. [TechCrunch]
