Personally, I generate a lot of long listings (e.g., complex sql
statements, where i use babel and org to build up a large query) and
not a lot of cross references.

That sounds like the most sophisticated approach. Still, as cheesy as
it seems, I think dropping lines of source code is a bigger
problem. The cross reference approach seems clever, but maybe a
simpler approach would simply be to add an ATTR_LaTeX(:longlisting)
and leave it up to the user. Currently, I've hacked my copy of
ox-latex as show above (ignore `label' as a float wrapping specifier).
