It is *extremely* simple. Have a look at packet-msn-messenger.c
and look at the handoff routine:

void
proto_reg_handoff_msnms(void)
{
  dissector_handle_t msnms_handle;

  msnms_handle = create_dissector_handle(dissect_msnms, proto_msnms);
  dissector_add("tcp.port", TCP_PORT_MSNMS, msnms_handle);
  data_handle = find_dissector("data");
  /*
   * For MSN Messenger Protocol over HTTP
   */
  dissector_add_string("media_type", "application/x-msn-messenger",
msnms_handle);
}

You only have to add the correct media type for YMSG to its handoff routine
and it'll be dissected accordingly!
