crossdomain.xml and clientaccesspolicy.xml

Will there be appropriate crossdomain.xml or clientaccesspolicy.xml files set up that will allow Flash and Silverlight applications to easily access the new API?

For those who don't know Flash/Silverlight apps can only access content on different domains then where the app is hosted if the sites has one of these two files with the correct settings in it. It is done for privacy and security reasons.
