The very first character I played in an MMO (RP wise) was a blind one. It can be quite fun but can also be challenging at points, which I enjoyed. I have quite the funny stories behind him as well. That said: I learned quite a bit from it.

It could develop naturally. As a blind person walks around and listens: you would develop more sensitive hearing thus allowing you to hear the bounce back of sounds off objects near you. If you listen to your own foot falls (with sensitive/developed hearing due to being blind for a while) you'd be able to hear when you're approaching a wall versus walking in the open. However, this, much like the aether thing, also would be rather difficult in busy locations since you are getting sounds from all around you and it would be much harder to focus on a specific one.
