Logitech Media Server repositories
SqueezeCenter 7.3 includes an Extension Downloader that provides a simple web interface for installing SqueezeCenter Plugins and Applets, Wallpaper images, and Sounds for SqueezePlay and the Squeezebox Controller.
In Squeezebox Server 7.4 there is a setting called 'Show all 3rd party plugins' in the Plugins tab which will enable all plugins in the repositories listed below besides those in the beta testing repositories at the bottom of this page
