Assign ID to all clients on server...
Example : number_of_cl += 1; my.id = number_of_cl
Use str_ functions and execute to assign a pointer with that ID to that entity and wait 1 second. Send the ID.
Client side , start a function that loops endlessly. In this function , go thru the list of entities , and if the current entity ID pointer is assigned , do nothing. Otherwise , assign it to that entity , again with str_ functions and execute.

If you dont understand it read it again...
