This "always-on" audio channel between you and your friend keeps the
intimate link alive and functions somewhat like a live chat room. A
panel of microphones and speakers creates an ambient soundscape which
offers an impression of what is happening in your friend’s room. At any
time, you can choose to virtually step in his/her space and converse
with your buddy as if s/he were in the room with you.
Personally, I avoid long distance relationships.
