I'd add a capability of storing net information along with lines, polygons,

Hmm... this could be incorporated into
4) DRC re-use: refer to a 'base' DRC rule, rather than re-describing
the DRC at every instance. DRC rules could be arbitrarily complex or
simple, e.g. elements in DRC class '250V' must have a 0.050" clearance
from class '5V', but can have 0.010" clearance within '250V', or
something along the lines of the 'skinny, normal, fat, power' we have
in place now.
A 'net' could be specified by a class/group of elements within which the
DRC clearance would be 0 and probably the minimum intersection between
two elements would be enforced as the minimum width for that group. If
elements are tagged with a net ID, including polygons, then that would
still take care of the 'new lines & arcs clear'.
