Disklavier

Has anyone heard or know of live Internet performances MIDI'd 
directly to the DKV?

Just heard Lang Lang on Live at Lincoln Center on PBS broadcast. 
Wouldn't it be fantastic to have your DKV play his live concert right 
in your own living room? 

For the technies, what would be the best way to stream MIDI with 
video over the Internet. Or just stream the MIDI, turn down the TV. 
Probably would be a slight delay? JTOL (just thing out loud).
