Connecting Yamaha Disklavier and NU1

[kclee6337]

My parents have a yamaha disklavier at their house, and I'm off at college. I just bought a NU1 and I was wondering if theres a way to connect them over the internet.
I've looked into internet midi. and came across zenph sound innovations. But apparently they went bankrupt a while back.
Does anyone know how to connect the two pianos wirelessly. I'm in a different city and they would like to somehow get Disklavier to play what I'm playing on the NU1.
