My polycomm knows me
you walk into a conference room; dial into a con call on the polycomm; the polycomm senses your bluetooth phone and (using a discovery service) looks at your personal attribute known as “music preferences”; thus your current favorite music (by how often you listen to it) is downloaded from your “federated” mp3 player — and the hold music while you wait for your fellow con-callers is *your* favorite music.
