I have iTunes DJ setup and my guests cannot access the library

I have setup iTunes DJ and it is amazing. I have setup in the settings tab to allow Guests to have access, to request songs and to vote on music they like. I ensure they are connected to the WIFI. When they download the remote application they are not see my library.

When they try to turn on HOME SHARING it tries to give an access code to pair with the existing itunes. There is no option or ability to just see the iTunes library that I have setup already. Does anyone have any idea what else I can do? Is this a setting on their iPhone that needs to be changed?
