Do I get this right: Setting Helvetica and Courier as default would not 
require us to add fonts to LilyPond's installer?

If this is the case I would ask for the following:

1) Set these fonts as default.
This is not sufficient from the perspective of LilyPond's aesthetics but 
it would stop the inacceptable state of scores compiling differently on 
different systems. This should be a straightforward, small patch that 
should be done independently from 2) (I just don't know where to start 
with that).

2) Find suitable fonts and include them in the distribution
I know this is a more difficult issue than 1) but I think it would be 
worth it. By default LilyPond scores don't use sans or monospace (IISC) 
but I think LilyPond should actually provide beautiful defaults for 
these too.
Maybe it would be a good start looking for fonts in the same sources as 
CenturySchoolbook?
