Ok.
Now Im using your second exemple. Only one more question, where is a good
place to start my socket (socket = try to connect), on the __init__ or in
any specific event?
My scenario: Im running three apps in each controller, con_manager_1.py
opens a connection to the con_manager_2.
Controller 1
controller 2
socket
switch.py/role_manager.py/con_manager_1.py --------------------
con_manager_2.py/role_manager.py/switch.py
Thanks. Sorry for all these many emails : /
