DjPandora is an application that interfaces with pypandora. The premise is to allow a group of people to control a single Pandora installation. The idea came about as a way for our office to control the office Pandora radio setup. This will allow users in the office to vote on songs, stations, and so on to control Pandora as an overall group.
Full documentation can be found at ReadTheDocs.
Uses PyPandora: https://github.com/amoffat/pypandora/ That provides the Python API for Pandora, along with an XMLRPC server for this Django app to leverage.
