Client side dropped item detection.

[kbillinghurst]

Anyone know how to detect when a dropped item's data is loaded in client side? Like say i used a command block to spawn in an item which had the name "lol", how can i listen to the packet that recieves that data and retrieve from a client? (For some background of what I'm trying to do: I'm trying to make it so a noise is played when a certain item is on the floor, the item has a custom texture from the server) 1.9
