// Special device which allows simulation of multiple listeners
// hearing the same set of sources.  Provides access to the rendered
// data for each listener.  Designed to work with LWJGL.

// first, the mainContext is the only context that is controlled by
// LWJGL.


// One context will be created for each listener that we want.

// Then, at the start of each render loop, we will iterate through all
// the active sources in our mainContext (the one which is controlled
// through LWJGL), and take their sourceIDs.  For each of these IDs
// and for each other context, we'll check some internal structure to
// see if we've already created a corresponding source.  If that
// source exits, we will SYNCH it with the source which belongs to the
// mainContext. If it DOESN'T exist, we will CLONE the source from the
// main context and establish it in the other context.

// Each render loop consists of noting all of the active sources in
// the mainContext and storing their IDs.  Then, for each context,
// the correspondig sources to the active sources in the mainContext
// will be set to PLAY, and all sources in all other contexts will be
// set to PAUSE. aluMixData will be called for each context in this
// way.
