Maybe you should put it not simply. USB already works as described with many apps, utilities and tools. For example, with QuickTime Broadcaster the user selects a device, a codec and a destination. With USB sound inputs or outputs the user can select drivers and encoders from preferences or within apps. Command line tools on systems other than Apple offer tools for selecting devices, encoding and destinations, which Apple offers in tools available in QuickTime or in the I/OKit.
