RealNetworks settled its antitrust lawsuits with Microsoft on Tuesday and walked away with not only a large sum of money ($461 million) but agreements to market its products and services together for 18 months. The total package is worth $761 million.

Here are some key aspects of the agreement:

• Non-exclusive: Microsoft is still free to partner with others and promote its own services.
• Promotion: Rhapsody's service will receive
• Integration: A new version of Rhapsody will download with every new MSN Messenger client and with every upgrade to the client. Microsoft will give Real access to and long-term licenses for Windows Media and security technologies.
• "We will pay Microsoft predetermined market-rate bounties for new Rhapsody subscribers delivered by Microsoft through the MSN marketing channels," said Real's Rob Glaser.
• Pricing: The Wall Street Journel predicts lower pricing for Rhapsody services to compete against Apple and Yahoo.

There's now speculation about Microsoft's plans for a subscription service, given this deal and the failed talks with major labels. Coolfer would like to see elements of MSN Music brought into Rhapsody, such as the easier method of purchasing tracks for download and an ability to access the store via a web browser (though it's hard to say if either is likely since Rhapsody will continue as a standalone product and competitor to MSN's services).
