SAM enables "download on selection"
I like to see SAM enable the creation of a community of audio messages that lets the SAM listener choose the audio messages they want to listen to. This preserves download time and bandwidth. Listeners could use the message title, description and other audio message attributes to make clear choices. Why download media that you are not interested in? Downloading audio or any media automatically at this time on the Internet adds unnecessary load and bandwidth costs to the SAM network.
Imagine waking up in the morning, reading your SAM enabled RSS reader from either your PC, notebook or PDA and picking and choosing a couple hours of audio messages. Then as you were doing something else, like getting ready for work the iPod using it's builtin WIFI or bluetooth (not available today) automatically syncs and retrieves your morning audio message picks. This process can be repeated throughout the day.
SAM makes the audio message chooser aggregator piece possible today and most importantly enables a community of available audio messages. SAM makes it easy to write SAM-aware aggregators and feed readers.
I have a hunch that MP3 players with WIFI or bluetooth are right around the corner. Stay tuned for their announcement at the end of next year. But what is the next feature after wireless networking is added to Mp3 players? Why not SAM enable it?
In the meantime we will just have to sync our MP3 players to SAM using USB or FireWire. Imagine how many new users will be receiving MP3 players over the holidays. All are potential future SAM listeners.
