What is the best way to integrate video chat into a website?

Question

I want to make video / audio chat (both individually and in chat), available on my website through a web browser, and no download is required. My end is php + mysql. What affordable (and free) solutions are there? What are their pros and cons?

Answer 1

I believe tokbox / openok - your answer :)

Notes: There is a free version and a premium version. The premium version provides archiving features.
