Benefits: 1. If a user modifies one, the other automatically updates and hence is always accurate and in sync 2. saves resources on the server (the number of nodes can be quite huge when the boundary becomes detailed over time) 3. boundaries can be better rendered by the server if it knows they overlap. If they were made of completely different nodes, it takes more computing resources to determine if they are adjacent. Same thing applies to overlaps between state boundaries. -- Harshad RJ http://hrj.wikidot.com
