Internally labeled as "Vega" (possibly referring to the star and not the Street Fighter weirdo), the service is expected to launch in early November with 10-20 games. The portfolio of Live-enabled casual titles will match the taxonomy of Xbox Live Arcade and hopes to be bolstered by 2-4 new games every month following launch. Potential users will be funneled to the service from numerous Microsoft outlets, including MSN Games and the official Xbox website. Much like Live Anywhere, Vega contributes to Microsoft's goal of spreading the Live experiencing across multiple linked platforms -- and likewise aims to entice more and more people with Live subscriptions.

At Gamefest 2007, however, Microsoft's official line was less clear. To deliver user generated content, developers can take advantage of what's called Xbox Live Silver Platform (XLSP), where the data transferred runs through the publisher's servers, not Microsoft's. Publishers then become responsible for what runs through it, monitoring and policing offensive content, etc. Taking advantage of it, however, requires Microsoft approval.
