The problem is that things get complex really quickly.  We're doing this
by pregenerating an image for every network and reference number that we
need.  Adding multiple variations for each route drastically increases the
work necessary to keep up with things, so I would really prefer to have a
single supported tagging scheme.

County roads, as I've written in another email, are something we decided
to defer until the US states and Canadian provinces are reasonable
settled.  I'm probably going to have to write some more tools to deal with
the multitude of counties that are or will be present in the database.

No matter how well it would perform, never construct any sort of machinery
which is completely indestructible except for one small and virtually
inaccessible vulnerable spot.
