Yes, the path of the station would oing-pong, but by being active, you  
could limit the positions sent and the load on on the system to the  
minimum, while at the same time assuring that the user's real  
positions only appeared on last position pages like findU's find.cgi  
for a few seconds.

Of course, if you do this, expect the users to get wise, if they are  
bootleggers they will start using different calls, maybe even ones  
that look like real calls.
