Some of the coolest, most innovative features about ooVoo are not the most heralded. The thing ooVoo leads with is the six-person video chat that takes up almost no bandwith based on a special new technology.  However, Web Workers Daily really gets why ooVoo is surely cool, even if you don’t consider the five-plus-oneself video and audio chat:

“You can also record and send video messages, even to recipients who are not ooVoo users. In a nice touch, they’ve leveraged their infrastructure for this to allow ooVoo to serve as a general file sending mechanism: up to 20 files at a time, each up to 25MB, which is nice if you’re stuck with email that throttles you down to unreasonably small attachment sizes. There are various other bells and whistles like click-to-call “ooVoo Me” links for your blog and importing contacts from your address book, but the video conferencing and video mail features are the clear core.” Via Web Workers Daily
