Apple TV as a DLNA server - aTV NAS >>X360

So now that I’ve setup SMB on my aTV, I’ve got a streamin bug. I’m out stream to everything in my house. TV’s, computers, toasters etc.

Does the 360 use DLNA to find computers? I use Rivet to stream from my Mac to my XBox 360. I know Nullriver’s Connect360 does this too but Rivet support more folders. Anyone have any insight to the inner workings of those kinds of apps?

And an even better question … can this protocol be used to stream media from a USB drive on the Apple TV?

I guess if worse comes to worst, I could dust of the ol’ XBMX original XBox and just mount the SMB drive.
