We're really proud of what we've built here, and we're looking for beta testers to help us continue to scale Mantis. Filling in the holes of commodity WebRTC is going to bring some really fascinating face-to-face video apps to the market a lot sooner, and we're excited to have folks come into the playground we're building and play a bit.
If you're interested in using multiparty WebRTC, then please email me at melih@tokbox.com
