Firewall software & using a remote control for AirTunes?

Question

I recently turned on the built-in firewall on my MacBook Pro. Ever since doing so, every time a run iTunes, get the following message:
Your computer is using firewall software that prevents
you from using a remote control for AirTunes.
To use a remote control for AirTunes, open System Preferences, click
Sharing, then click Firewall, and select "iTunes Music Sharing."
I always tell it to "Ignore" and I am able to play music through my AirPort Express without any trouble. What is the "remote control" to which this message is referring? I have searched Apple's support pages and this forum without any luck. I thought that opening the "iTunes Music Sharing" port in the firewall would allow other people on my local network to see my music if I was sharing it, which I am not. I don't see what this has to do with a remote control.
Thank you for any info you can provide.

Hi,
there is no remote control for AirPortExpress or Air Tunes. Maybe we will see something like this in the futue, who knows.
As AirTunes uses streaming, it probabely needs the same port open as Music Sharing. Because shared music is streamed too.
