  • How do we scan for music?
    • Use a client/server arrangement where the server scans and the client queries similar to UPnP
    • Scan on startup
      • How fast can this be?  Don't want to wait minutes (even 1 minute would be long)
    • Scan on startup but save in file so subsequent scans can happen in the background
      • How big would the saved file be?
      • Reading the file in should be much faster than scanning
    • Could have two programs; a scanner and the jukebox
      • Scanner is command line only and scans directories and build database
      • Jukebox read database
