Microsoft job posting hints at cross-platform Zune environment?

We've heard Microsoft make vague references for some time about a Zune-like experience involving non-Zune devices (Windows Mobile phones, Xboxen), and it looks like they may be making real moves in that direction. A recent job posting from Redmond for a "Software Development Engineer in Test" calls on someone who "dream[s] about having a mobile phone based entertainment experience powered by a unified entertainment service across devices such as Zune, Xbox and PC." Someone, the ad reads, who will, "create a 'Connected Entertainment' experience, realized through the Zune service, that spans multiple devices such as Zune, Xbox, PC and Mobile phones." Sure, it's not exactly a bold-faced advertisement for a cross-platform Zune environment -- but it's pretty damn close.
