Has anyone attempted something like this yet, and if not are there any limitations that you can think of that would make it not-feasible (other than personal ones like how much weight you can safely have strapped to you)

I have a Sager laptop with a 980m GPU and a Skylake processor that on paper should be able to run the Vive without much issue. If I were to make a backpack style mount for the laptop, and attach it and the break-out box to a portable battery like this one http://www.amazon.com/ChargeTech-Portable-Universal-MacBooks-Motorola/dp/B0116BX968 , is there anything stopping me from having a wireless (at least from my body) VR setup?

Throw in some powered lighthouses and i could take it anywhere to play as well. Outside in the backyard at night, office room at work, gym at church, etc.
