wireless remote focus from a tablet/pc

I think i already know the answer but is there any way of setting up a wireless remote focus off a laptop via a roadhog, if no which i think is the answer what would be the cheapest way of setting up hog 3 pc and what hardware would be needed to be able to roam wirelessly but still have the full availability of 4 universes out of the roadhog??

Thanks in advance

Mike
