pc-ble-driver-py more dongles

Question

Hello I would like to use more dongles with pc-ble-driver-py. For example I want to create multiple advertisers and test that my DUT would see multiple advertisers. I tried to reuse your Advertiser.py example. 
 The script crashes when I try to open 2nd dongle (calling driver.open() ) 
 
 Is there a way how to use pc-ble-drive-py to connect multiple nRF51 dognles? 
 If not then are you planning to implement such a feature? 
 If yes when we can expect such a feature?

Here is a working example with two advertisers: 
 import sys
from multiprocessing import Condition, Lock
from pc_ble_driver_py.ble_driver import BLEDriver, BLEDriverObserver, BLEAdvData, BLEEvtID
import multiprocessing


class TimeoutObserver(BLEDriverObserver):
 def __init__(self):
 self.cond = Condition(Lock())

 def on_gap_evt_timeout(self, ble_driver, conn_handle, src):
 with self.cond:
 self.cond.notify_all()

 def wait_for_timeout(self):
 with self.cond:
 self.cond.wait()


def main(serial_port, name):
 print("Serial port used: {}".format(serial_port))
 driver = BLEDriver(serial_port=serial_port)
 observer = TimeoutObserver()
 adv_data = BLEAdvData(complete_local_name=name)

 driver.observer_register(observer)
 driver.open()
 driver.ble_enable()
 driver.ble_gap_adv_data_set(adv_data)
 driver.ble_gap_adv_start()
 observer.wait_for_timeout()

 print("Closing")
 driver.close()

if __name__ == "__main__":
 p1 = multiprocessing.Process(target=main, args=('COM45', 'adv1'))
 p2 = multiprocessing.Process(target=main, args=('COM46', 'adv2'))
 p1.start()
 p2.start()
 p1.join()
 p2.join()
