Get user info from Myspace/facebook/bebo using cURL

Is this possible?!

Hi,

I'm making a social networking site and I'm looking into an easy way for people to get signed up.

Was just wondering if this was possible:

Could a user put in their Myspace/facebook/bebo username and password then a script would remotely connect to the site and grab their user info and avatar etc?

We're thinking that this would make it very easy and simple for people to join up, as they don't have to enter all that information again.

I presume I'd be using cURL for this. Would their be any obstacles in my way?

It is possible, but there will definitely be some obstacles. Like handling redirects, maybe parsing some javascript code.
