I suppose an alternative to backpacks would be a hybrid solution with "smart" headsets (much like cardboard/daydream) and a tradeoff in cpu/bandwidth doing some work on the pc, and some on the headset - and streaming over wlan. But I don't know if that's really feasible wrt getting the latency low enough with a high quality display.

DisplayLink already has a working wireless adapter for the Vive. I've tried it, and it's really good. No need for gimmicky backback computers or non-replacable headset computers.

I thought the issue with current wireless technology was getting the latency down, in order to work with true ~90hz refresh (so when you tilt your head looking at the horizon, or move your head quickly the display updates in seemingly real-time, not showing you one or two frames of old data).

Is this still not an issue?
