GUI agnostic - there should be a clear separation between front end and 
backend.  LilyPond is technically already GUI agnostic, as joe and vim (my two 
favorite GUIs) both act commendably as front ends to my LilyPond code.

The best thing, by far, would to make LilyPond a modular engraving library with 
public APIs for each module.  This way, building a GUI just means mapping 
visual symbols to API calls and displaying the result.

GUIDO (for which I’m a developer) already works like this and has been embedded 
in several commercial and open-source apps.
