In my opinion, this feature is one of the major design philosophies
behind Lilypond, namely that most of the Lilypond code only
describes the music, whereas the typesetting details are determined
by the engraver definitions and property settings, all of which
can be done in the \paper section. By preparing a number of different
initiation files with \paper{} declarations, you could use the flag
`-i' to lilypond to select the desired layout or MIDI definitions.
A possible improvement would be to allow for several -i declarations
on the command line and also to add a corresponding flag for ly2dvi.
On the other hand, then you'd soon begin to use Makefiles or 
scripts to remember which combination of added init files produced
which version and you could just as well get the same function
using a .ly with a number of includes.
