I understand this.

Is I stated before there should be the possibility to add some other 
output views. If they are JSON or whatever format somebody likes.

The main work I do at the moment is not the reformating of the textual 
output but doing some restructuring of the data model
to implement a bit more model-view-controler style.

If the data model is cleanly defined it is a simple task of writing one 
C-subroutine to implement an status output of any flavour
somebody likes.

But I hoped to get a bit of support from the original developers since 
they know best how to modify there data model to achieve this goal.

Please support me with the desired output for your case and I will 
implement a corresponding output view for you.

Best Regards,

Volker
