I've not read the code, so maybe this thought is completely off-point,
but I wonder if anything could be learned from PostGIS.  AIUI they
have developed the infrastructure needed to have auxiliary info
(particularly, spatial reference data) attached to a geometry column,
without duplicating it in every value of the column.  Seems like that
is a close analog of what's needed here.
