Thoughts on replacing the DBM radar

[natinusala]

You all know that the patch 7.1 broke all the API functions used by DBM to display the radar in an instance. I saw in a forum that "they can't prevent triangulation". And it had me thinking : would that be possible ?

Every player has their distance relative to every other player, right ? So if there is at least 3 other players, there is a way to have an estimation of the position of each player within the room by using triangulation.

Each addon would need to send a list of all the distances to, let's say the leader of the group, which can then compute a map and send it back to the players. Just reposition the map using the player's known position and you've got yourself a radar. An update frequency of 1-2s should not be too heavy, I guess.

What do you think of this ? Is anyone already working on this ?
