The spec for MTP is not too hard to follow: http://www.usb.org/developers/devclass_docs/MTP_1.0.zip MTP includes very minimal DRM, essentially just a way to flag files as having "DRM protection" or not -- see "DRM status" in the above document. This doesn't mean that MTP "has" DRM. All it means is that the file is encrypted in some way that makes it hard to play on another device (like Apple's .m4p files). In other words, it's just an extra bit of metadata about the file. This however: > Apparently this is a key part of MTP. > http://msdn.microsoft.com/en-us/library/ff632508(prot.20).aspx is an MS extension to MTP. No idea if anyone apart from Microsoft implement this nonsense. It doesn't appear to have been inflicted on any Android devices I have, and since MS have about 0.001% of the worldwide phone/MP3 player market you probably won't see this in the wild very much.
