This packages is a combination of software and hardware which makes it
possible to send audio inside an ethernet cable and send IR signals
from regular remote controls in the opposite direction of the audio,
and at the same time still use the ethernet cable for 10/100 ethernet
traffic.

This is useful if you like to get your computer sound from your computer
room into your living room, and at the same time be able to control the
computer using remote controls from the living room.
