Disklavier

Hi.  I have a wireless & wired network in my home.  I use my laptop 
via wireless, and would like to run VanBasco's player to send MIDI 
songs to the piano.  However, I don't want to have to put the Laptop 
in the living room next to the piano to do this.

Or, I'd like to be able to control the piano from another (wired) 
computer in the kitchen.

I have a computer in the basement room right under the piano in the 
living room, and could run the Midi Cables from there through the 
wall and up to the piano.  

So, I'd like to be able to route the Midi out from my laptop or 
kitchen desktop over my home network to the computer in the 
basement, then to its MIDI card and up to the piano.

Alternatively, this could be done via wireless MIDI, but I've had 
trouble finding anything on this, except for some standards that are 
in development -- no real products yet.

I'd really appreciate any advice and practical experience.

Thanks everyone!
