That's the point. In client side API there's 
playerc_client_set_replace_rule() function which sends 
PLAYER_PLAYER_REQ_ADD_REPLACE_RULE request while I can't see anything like 
that in driver side API. I'm thinking about sending this request directly, 
but I don't know yet on what object shall I call Request() method, I guess
there's no client object on driver side, so there must be something else 
on which I can call Request() (or there's a method in driver API that do 
the thing better/safer).
