That idea with PWM on LEDs isn't bad, but LEDs have also some time to turn off completely (but I don't know very much about transfer via light system).
Have somebody tested that host mode? I don't know how to switch it so.

Diags is not GPL, so probably not...
Incandescent bulbs take awhile to turn off because the filament needs to cool. Fluorescent bulbs take awhile to turn off because the phosphor had a decay rate. Some white LEDs contain a phosphor that is activated by an internal blue LED, so those white LEDs are actually a type of fluorescent light.
Ordinary LEDs turn on and off fast enough to send Radio Frequencies over them, so they would certainly be good enough for audio use.
