While the value proposition of pay as you go VoIP from Zoom may have been around for some months I really think this is a good idea, especially for Nomadic types who need to make calls.
Zoom has a package called Global Village that is pay as you go for VoIP. It eliminates the contract and monthly minimums, but it appears to lack any ability to make inbound calls. I recently saw their telephone adapters show up on store shelves in the USA, but with today's announcement it seems they are going global in a big way.
