iPhone remote multiple libraries - what it means

The iPhone Remote app supports connections to multiple libraries.

Macworld | iPhone Central | Remote lets you control iTunes from iPhone, iPod touch

...There is, however, support for multiple libraries. When you start up Remote after associating with a library, it’ll take a second to reconnect, during which time you can change which library you want to use (you can also tap the Settings button in the top left corner of any list screen). That’ll give you the option to add multiple libraries, delete existing associations, and toggle a “Stay Connected” preference (not precisely sure what that does at present)...

The implications are left as an exercise to the reader.

Ok, some hints:

1. iTunes is designed for a single user. It belongs to a user account.
2. iPod and iPhone binding is not to a user, and not to a computer, it is to a user account on a single computer. Unless everyone wants to share apps, contacts, calendar, etc a single iPhone syncs with a single iTunes library.
   
3. DRM contracts are to a single user's Apple identity (formerly .mac), they can be applied to > 1 computer (the number is shrinking over time).
4. DRM is far from dead. If the music industry succeeds in toppling Apple by allowing only Amazon to sell without DRM, then they will terminate Amazon's DRM-free privileges and assume the throne of Sauron. (You knew that, right?)

It's a complex world. Looking at the way the iPhone works, it's possible that we could move to a family account that all devices would sync to -- since iCal supports multiple calendar overlays and Address Book supports multiple subsets. Gives a whole new meaning to "all for one and one for all", a meaning of particular interest to teens.

Consequences, intended and otherwise ...
