I agree with all of the above.  If you don't need the speed, it is
best to let the server handle it.  A couple footnotes, though.

Various studies indicate that computer response times of 150 ms or
less are not percieved as delays.  I wish I could find a source for
this.

Also, I remember Raph mentioning that UO was never intended to be a
twitch game where reflexes were critical.  So never forget that what
you write your game to do and what the players try to do with it may
well be entirely different things.
