In the proposed protocol, there is no 'MOVE n' command.  Instead there  
is a 'MOVE <player-tag> <x-loc> <y-loc>'.  A server which receives this  
command will try and move the player to the named location as fast as  
possible by the straightest route.  Losing a packet under these  
circumstances can still be annoying, but it isn't quite as bad.

Yep, that is one benefit which we would lose.  But there are others.

But please don't misunderstand me -- I'm not arguing in favour of a UDP  
protocol, at least not know.  I'm just trying to point out that if done  
right and with enough work you can probably reach a point with UDP in  
which the advantages outweigh the disadvantages.
