Took existing siberia site home page prototype and added some php and javascript to it to store the language as a session variable (I guess I could have done it as a cookie, not sure why I didn't). Amounts to an Ajax call that just updates the value of the session variable and then reloads the page. Also allows for lang to be passed as a get variable in the URL to force the language of the page. If no lang variable is passed, then page checks the session variable for value, if variable has no value, then it is set to English.
