Just pipe the output of a custom backend to another tool. With a simple, 
consistent and *complete* representation of the data, this is the next step.

That's just normal, as every application does something only it can. Why 
should it exist otherwise?

You can add custom data to an variable in lua, so this data can be saved 
inside the core too. http://www.lua.org/pil/28.1.html

We habe to break some eggs to make an omelet...
