I wonder if you could multiplex the signals from a bunch of nerves and send them over an Ethernet link.

A radio link would simplify this enormously. You could link nerves "wirelessly"from a leg to near the brain without any surgery in between. I don't see why it's fundamentally impossible?

  After pressing the button on the microwave you'd be frozen until the machine beeped. Unless you had a tinfoil hat (well, suit).

    Typically, you close the microwave door before starting it.

      Just remember to close it from the outside!

  I'm not sure it'd be a brilliant idea from an infosec point-of-view - the links themselves would need to be hardened in such way interfering with them would be impossible, or someone would be able to just blast the proper messages to the receivers to take over someone's body. In fact, the conductor was half-joking. I'd probably go for fiber, even if it adds latency at the endpoints.

    Radio would be awesome because you don't have to force some cable through half the body, which must be real major surgery. Some pretty basic encryption scheme should handle infosec angle.

Next level: link together a group of humans. I can't really imagine the implications of that, but I think of Vernor Vinge's "A fire upon the deep" and the group minds of the wolves there...

  Hmm, you could have a skilled pianist play piano through your hands.

    There's more than that to playing - a musician masters their own body in order to play the instrument with the required dexterity. There would need to be a translation layer between the commands that work on their body and the ones that'd work in yours (different finger lengths and muscular strength is the first thing that came to my mind).

      I was rather thinking about instant communication and cooperation, instead of remote control. Like an entire orchestra tuned together - no more individual players but one orchestra superbrain. Or football team. Or of course army shudder
