How were you thinking it would work differently to a 'simple snap'?

Working with PostGIS, I snap to the nearest node (rather than edge), and
then also record the distance and add this in to the total. Many commercial
solutions (eg. Microsoft MapPoint) also do this: Record the distance to/from
the closest road and add this in to the directions and distances.
