Has anyone thought about the Arc/Info coverage model? The idea would
be to have a table with line geometries and attributes reflecting the

Absolutely. Much thought has gone into this already ... even a little
development ... but I'm afraid that's where it stopped.

My thought is you do your edits on the line geometry table and then
polygon topology is built in a separate (dependent, inherited??) table
based on the line table using well defined procedures. The only
function I don't see offhand that is not there is a split polygon
with line. Just my thoughts.
