Hi,
I need advises for a tool to integrate to our web site. This tool will provide our users to do face-to-face online video talk and chat.

I did a little search on web and see arrowchat and cometchat tools, however I could not find more deep information on them.

Please advise me a thirdparty tools for this purpose, easy to integrate, cheap or free, with good performance, with good graphics, etc...
