iTunes Visualizer on a PC and Scratch Live on a Mac sync with eachother

Hello
I am working with a friend using scratch live and the iTunes visualizer. We each have our own computers (1 mac, 1 pc). He knows how to use Scratch Live and I wanted to play with the iTunes visualizer. Is there a way I can have the iTunes visualizer on my computer interact with the music he plays from Scratch Live on his computer?
