Is it possible to aggregate user statuses from Twitter and Facebook using javascript client-side scripting only?

I would like to make a web page that aggregates social sites like Twitter, Facebook, and others however I have no idea if this is possible considering cross domain security issues.开发者_StackOverflow社区 I've heard of JSONP but I've never used and don't know if that will work to get data from Twitter and Facebook.

Check out http://remysharp.com/2007/05/18/add-twitter-to-your-blog-step-by-step/ That shows a JS based solution to get a timeline just through javascript. I presume you can do something similar for facebook (?)

Neither Twitter nor Facebook provide JSONP.

You might be able do a javascript only aggregator site though using their javascript apis:
