It’s a very easy video conferencing system (though it also appears to work if you just have a mike and not a webcam). It’s similar to MeBeam and Tokbox two other online video conferencing sites on that list. Those two allow you to just use microphones for audio if you don’t have a webcam. MeBeam lets up to eighteen people participate, while Tokbox lets up to “20-25” (at that point, there’s some deterioration in audio/video quality).
Meeting 24, however, allows up to…24 people to take part.
Thanks to TechCrunch for the tip.
