How about this plan:

1. s/json/yaml/
2. s/hardcoded props/default props yaml file/

The 1st item would let us get rid of jansson library (yaml for the
sake of keeping list of props can be parsed by hands with the 
comparable amount of code). The 2nd would help us keep the list
of props up-to-date easier.
