More countries listed than Skype.
Still trying to figure out the viable business model. But hey, this is frackin' shiny!
But before you wet your pants, not surprisingly the Philippines is not on the list.
But if you have OFW's/Friends/Family members on those countries listed then you can call them for free. I wonder if that constitutes an operator bypass? And if this is similar to Skype which restricts the service to chosen countries. At any rate, this is based on top of the net infrastructure, so there are ways to route your packets.
VOIP is an emerging tool in making the world flat! Definitely, something that could bring a smile to Thomas Friedman. :D
