Xbox 360 to play content from a bunch of non-Microsoft devices?

So we know from the Xbox 360 E3 event that the Xbox 360 will supposedly be able to magically speak to the PSP and the iPod for some serious portable media integration. This point alone might be worth bringing up for discussion now that some of the dust has settled, plus the recent comments from Shane Kim of the Xbox 360 division are indicating an even higher scope of integration envisioned for the console — including interoperability with all types of portables, including PocketPCs, palmOne handhelds and Bluetooth-enabled cellphones, among others. In other words, the goal seems to be support for accessing content on just about any conceivable portable device for playback on your TV via the Xbox 360. Yay, we support the idea — but we're concerned about how they're gonna implement all of the above technoutopia in the age of DRM lockdown. Are we really gonna see .M4P playing on our Xboxen? We're all ears.
