What is a software solution that provides 1 on 1 video chat?

We've made an application where two people can video chat with each other using TokBox, but are running into a lot of technical issues surrounding WebRTC and TokBox itself. I know that Twilio recently launched a Javascript version for their video service, but both TokBox and Twilio seem to be aiming for larger scale publish/subscribe operations. It also isn't as far along as TokBox.

Are there other services out there that can do web video 1 on 1's? Perhaps some that don't use WebRTC and therefore don't have the problems we are facing?

I can't help but to think back to ChatRoulette and similar apps.
