Apple should remain tight about this and not give it to anyone
DLNA enabled sets already allow manufacturers to do this. It is a standard that is supported by many devices not made by Apple. It currently allows an easy way to stream video and audio from pretty mych any device wether they are wired or wireless. It also alows any file type to be played, not just the ones apple tell you you can use.
New Samsung TV's already support wireless streaming so trying to get Apple to join in will just ruin pretty much the only time the correct technology has been used from the start.
