Audio video chat with the ability to embed it on your site.
Can widget chat service or server software. It would be ideal if you have developed API, the possibility of localization, scaling from chat for two to the level of the webinar with additional services like whiteboard'. If users do not need installing additional software or browser plug-ins — it's great. And, of course, neopredelennoe price, or free/open source status. :) A combination of at least a few of those wishes real?
What would you recommend?
