Seems that would be relatively easy to write for TIGER data.  I'm not
sure how useful it'd be, though (especially in the areas with decent
aerial imagery available).

For areas without decent aerial imagery, maybe if someone rendered the
latest version of TIGER as an "underlay", for tracing.  Combined with
a checklist of areas which changed....  I don't know, the places I map
generally have good aerials available.
