Qantas are doing streaming in an app for some domestic planes now (pretty much all the ones that hadn't got the upgrade to the seat-back screens - all their planes that fly international have screens though). It's actually really good - an iPad has a way better quality display than anything I've ever seen in a seatback and the content library is larger if anything. All they have to provide is a USB charging port and a thing sewn into the seat that you can hook most cases over.
