Yes, the only alternative I've found in the short term would be to use 
something much, much simpler like this (code in public domain):

I fully agree with your point about not spending time on the wrong thing 
before Berlin. So which is the lesser evil? Less fancy CLI, or LGPL?

(unless someone else comes up with another alternative of course)

What I've seen done before in embedded CLIs is basically just an input routine 
and then a big case statement. Not pretty, but functional.
