- If you want to make direct calls to Twitter or Facebook APIs from the client (either via jQuery or via the provider's own JS API), you'll need to get the access token from the server side to the client side somehow to be able to properly construct the requests. This is a bit hackish, though.
- It's a bit more work, but I believe the best way is for you to provide your *own* REST API that the client talks to. That API would then make the calls to FB or Twitter from the server-side on behalf of the client.
