On 06.06.08, we launched a new feature for Flash developers:
Allowing script access. A lot of questions have arisen about this lightly
documented feature.
In a nutshell, we are now hosting your flash files on the
MySpace server. This changes our security model, allowing you script access!
Here’s a snapshot of what you should see when you upload a flash file:

As you can see, there is now a cached version of your SWF,
as well as a place to edit the Flash Markup. Instead of using FlashVars, you
can now get an OpenSocial token and the rest of the OS goodness.
Okay devs, start updating that code!
