(Digital Audio Access Protocol) The Apple protocol that shares iTunes playlists with users across a network via their computers or media hubs. iTunes uses Bonjour to discover devices on the network and DAAP to make the playlists available for sharing. Servers and Clients A DAAP server is the software that makes the playlists available, while a DAAP client is the user's music software or media hub in a network. Although iTunes is both DAAP client and server, a variety of third-party software provides one function or the other. For example, Rhythmbox and Banshee are DAAP clients running under Linux, while Firefly Media Server and Tangerine are DAAP servers that run under Linux as well as Windows and Mac. DAAP clients are also implemented in hardware; for example, Microsoft's Xbox and Roku's Soundbridge media hub are DAAP hardware clients.
