In addition, MySpaceID now lets members broadcast their profiles' activity streams to external sites, while giving the participating sites the option to select which types of actions they will show, such as photos or music, while filtering out others that may not fit in with their focus.

Soon, MySpace will make this activity stream broadcasting bi-directional, letting members publish actions they take on external sites into their profiles.

MySpace is also announcing what it calls a big milestone for its data portability system: an early test of a MySpaceID application for Yahoo's . The application will let people log into their MySpace accounts from Yahoo.com and perform a variety of actions, like reading friend updates and changing their status message and mood icon, from within the Yahoo interface.

For developers, MySpace is introducing a new workflow that it says will streamline and simplify the process of creating and configuring MySpaceID applications. The company is also releasing a test version of a software development kit designed to also make it easier for developers to build MySpaceID applications. Initially it will have client libraries in the PHP, Python, Ruby, .NET and Java programming languages.
