Possibilities really open up with the telemetry translation api -- realizing that the telemetry is digital, and only has to be encoded once to be read for any purpose for any supported device is huge. We expect to be very busy for a long time fleshing out all the applications we have in mind. One that we're working on is using a users webcam to monitor heart rate (similar to the xbox one + kinect) and use that information to create a soft vibration that pulses in their partners device in time, so when one gets "excited" the other can feel the haptic feedback and vice versa simultaneously..
This is some real scifi stuff we're doing and it's very exciting
