It is recommended that you study ladon.interfaces.jsonwsp to learn howto extend Ladon with more protocols.
Currently you have to add an import statement in the bottom of ladon/interfaces/__init__.py to add your protocol to Ladon. This is a temporary solution.
Like this:
import ladon.interfaces.soap
import ladon.interfaces.jsonwsp
# My CORBA implementation
import ladon.interfaces.corba
