dynamic map objects or how I learned to love Rube Goldberg maps

Anyone find a way to place objects on a map which can be dynamically updated?

I guess I am thinking something along the lines of a blade chassis with blades, or a rack with u-positions, or a map with coordinates. We place the objects on the map in the correct location then somehow update when the object when the underlying node or such moves.

I am thinking I can do this with groups where group membership is driven through dynamic query but I doubt I really want to add 100's of groups - it's slowing our account limitations based on group s already - imagine if we tripled our groups arghhh!

Cluster 1

-Chassis1

--Blade1

--Blade2

--Blade3

--Blade4

etc where the group objects for Blade1-4 are placed on the map above and updated by location custom properties.
