Yahoo Query Language and OAuth

I was looking at this article:

http://www.yiiframework.com/wiki/35/how-to-connect-with-twitter-from-yii/

I have to search for users across multiple social networks. I was wondering if I could get the same result by searching through the yahoo yql community tables for twitter and also the other social networks, specifically http://www.datatables.org/twitter/twitter.users.search.xml

http://developer.yahoo.com/yql/console/?q=show%20tables&env=store://datatables.org/alltableswithkeys

Does anyone know if the yahoo community tables require oauth like the twitter example above? Will I just have one oauth connection to yahoo, or would I have to connect to the other social networks in the community tables with oauth as well?
