Remote control, but not on the server

[Jellelle]

Hi all,
I use the RC-button on my android-app so I remote control the server (which is connected to my speakers). This works great!

But I have a question:
Now I'm trying to figure out a way to remote control an other pc (connected to another set of speakers).
I can do this by using xbmc and the subsonic addon on the second pc, so I can controll it with the xbmc remote control app. This works, but some functions are broken.

Is there a way to get it to work properly?
Thanks in advance,
Jelle
