Hi Irmen,

thank you for your answer. I have two follow up questions:
1) From the docs I understood that autoproxy feature affects how
pyro objects are passed 
(https://pythonhosted.org/Pyro4/servercode.html#autoproxying).
In the example I have provided at the beginning this post thread, the 
class attribute has not been registered, so its not a pyro objects. It 
is being returned and the return value (copy or proxy) is affected by 
autoproxy setting. Does this mean that if class is registered then all 
attributes are registered as well?

2) In my speficif case, the autoproxy ON is ok, but in some specific 
cases I would like to receive a copy instead of proxy object. Could be 
autoproxy behaviour altered for specific call or what is the suggested 
way to get a copy?

Thanks,
Borek
