No free software. Theres no point in replacing one closed system by another, especially when the first one works much better. Googles system is only accessible through Gmail, is very awkward to use and has the "irrelevant addon" feel. Had Google _ever_ intended to offer widescale Voice&Video, they'd have built video into Gtalk when they had the chance.
Actually, Google's video/audio calls work in the browser. Not only is the software free, but you already have it.
You mean that only the browser is software, but not what runs in the browser?
I'm guessing the parent was referring to FOSS, not free as in free beer.
