Disklavier

Does anyone know if there is a way to connect a PC to a Disklavier with 
a wireless device.
I have my computer connected to my PC with a ""UX16 USB-MIDI interface" 
cable. The problem is that the Computer is not next to the Piano. So I 
do not like having 25 feet of trip hazard between the two. Especially 
when I have a party.
The only other solution I know of is to buy a dedicated laptop for the 
piano.

Thanks
