Netflix uses its internal Hack Day competitions to encourage new thinking around its streaming video service, and its latest event has produced a few clever experiments that we wouldnt mind seeing in finished apps. One of them, Netflix Beam, uses Apples Bluetooth-based iBeacon technology to share Netflix videos between iOS devices just by bumping them together. Another effort uses a Fitbit to check if you fall asleep mid-movie; if you do, you can resume from the point where you nodded off.
