DBC is being used by comma.ai see https://github.com/commaai/opendbc

I've been documenting the Leaf Can bus using KCD and I built a man in 
the middle for the LBC controller with can4python. It turned out fairly 
ugly because can4python doesn't support multiplex signals. 
https://carrott.org/git/leaf-can-utils.git/blob/HEAD:/nissan-leaf.kcd 
and 
https://carrott.org/git/leaf-can-utils.git/blob/HEAD:/nissan-leaf-mitm.py

I haven't had time to do it, but I'd really like to implement multiplex 
signal support in can4python so I can simplify the mitm.

I'm not sure why so many open source can bus efforts have been abandoned 
before they're fully done.
