If you're looking for the full video chat experience I think FunYo offers something very close. Funyo has the ever familiar roulette style chat that seems quite busy most of the time. They also have local and group chat options available, group chat allows you to chat with up to 4 strangers at once. Local chat provides quite a big list of cities and a few countries, the busiest of which is the Worldwide chat.
Quite a pleasant surprise considering all the ghost towns I've been coming across lately.
