i think so, yes. i'm not yet sure about the two frontends, but i don't
think there's a better way.
Switching could be done with the (currently undocumented?)
DMX_SET_SOURCE call:
#define DMX_SET_SOURCE _IOW('o', 49, dmx_source_t)
typedef enum {
DMX_SOURCE_FRONT0 = 0,
DMX_SOURCE_FRONT1,
DMX_SOURCE_FRONT2,
DMX_SOURCE_FRONT3,
...
} dmx_source_t;
So you need only one adapter, but more than one (virtual?) demux.
