There will likely be no further development for this since the newest versions of the download packages include support for process priority handling with NICE. Just FYI. I did find a solution when I was trying to make this happen though. I found an xbmc plug in that would run a script when certain xbmc actions occurred (play/pause/screensaver start/screensaver stop/etc). I ended up running a script to stop the services when the screensaver stopped and start them when the screensaver started. That gave me pretty good responsiveness when I ran it. Sorry I don't have the name of the plugin since it was many installs ago.
