Mulitplayer arcade? Not a support question

Hi....I put this here as it is not a support question...I have successfully created an arcade on my forum...but if this is still the wrong place please move it other than locking it, thanks

My members love the new arcade I have created as it gives them something to do during the season break of Lost, and have asked if we can have mulitplayer games embedded. For example, a 2 player version of backgammon that other members could watch.

I have found one site that offers this but they charge $99 a year for the privilege so...no thanks lol.

Does anyone know of any websites that I could get this kind of game from?

Thanks in advance.
