I use Pyro only locally in a secure environment, to avoid the 
limitations of Python parallel code (ie, no GIL) and improve reliability 
(ie, each node can run/restart independently). So I'm not personally 
interested in making anything more secure ;-) I guess having @expose 
working also on a class, or being able to select the expose mode via an 
argument of Daemon.register() would both work fine for me.

Actually, I'm now working in a spin-off from TUDelft: Delmic. We make 
microscopes: https://github.com/delmic
