Okay, but if the LOS calculations are done on the server, you have to transmit EVERYTHING  
THAT'S VISIBLE, every time you move.  At minimum, the server would have to transmit an  
on-off packet which would represent squares that're visible and squares which aren't, along  
with new squares that have come into view.  If the client is aware of the map, either having it  
locally or via transmission, it has all the information about the map already.  The only thing the  
server has to send is updates in x, y coordinates for items and monsters.  All LOS calculation  
and displaying of the map is done by the client, vastly reducing the load on the server, as well  
as transmission over the wire.

Sure, but taking a bully's sling-shot away doesn't mean he can't go out and get a BB gun or a  
two-by-four.  I'm sorry, but your analogy doesn't hold water.

If there is a concern about cheaters, the sysadmin can delete a user's character, or someone  
could implement a forbid-type thing for users and/or hosts.  Just don't allow cheaters to play,  
it's that simple.  Sure, you couldn't always detect cheating, but no one really can all the time,  
can they?

It may not be really compute-intensive, but it forces more reliance on the server to do things.   
We live in a distributed computing environment with computers that are more than capable of  
sharing the load of computation.  So, why limit yourself so much?  Especially intentionally.  It  
just doesn't make sense to me.
