I've looked into this too, although I've never coded anything
for it.

That works well if the vision range is one adjacent room. If the
vision range is more than one room, it can get messy. For example,
if your vision range is 3 "rooms" away, and if the average room
has three exits, then you can see 3+9+27 = 39 different rooms
in addition to the one you're in.

Indeed, and that's a pain. My application is such that I only
need notify players of the presence "in the distance" of other
players, and perhaps a short list of other objects. If I ever
go ahead and code this thing, I'll simply sweep through the
whole list to see which ones need to be reported, and each time
one moves, I'll check to see if any other player needs to be
notified of it.
