Dynamic, rule-based borders between polygons

Hi all,

I've been working with a polygon feature class that looks something like this:


Wherever two polygons of different types (shown above with different colors) meet there needs to be a thick dashed line between them. The solution so far has been to keep a separate feature class for the lines, which of course needs to be updated every time the polys change. This has gotten to be pretty tedious and is creating a lot of redundancy in our data. Is there any type of map layer that can be generated on-the-fly based on spatial relationships and attribute data of a feature class? I'm guessing a geometric network would be involved, but that's all I've got. Does anyone have any insights?
