We are developing a social website and hope to implement video / audio chat for users (people the user is friends with). Most of the technical team talked about using flash. But I do not want users to install something. Can video / audio / conferencing be done exclusively in AJAX? Either develop it from scratch, or use open source frameworks, if any?
Flash is already installed on almost any browser - except for iPhone, iPads, etc., which are likely to never support Flash.
