Is it possible to display the streams from different fan pages (that I'm not an admin of) to a website? For instance can I show all the updates from the fan pages of DigitalPoint, HuffingtonPost, etc. on my website without having to go to Facebook?
yes you can as long as you knew the profile id of a fan page, <fb:fan profile_id="123456789" stream="1" connections="0" logobar="0" width="600"></fb:fan> Code (markup):
true you have to know the profile id or page id then go to this url http://developers.facebook.com/docs/reference/plugins/live-stream/ and test
