Flash network diagram

I am looking to create a flash interface to graphically show my network devices and how they are linked. Something like [login to view URL] The node tree need to come from an xml file generate from a servlet and refreshed every N seconds (you dont need do the servlet, just read the xml file formatted as you define) - There will be an overview of the network, if you click on a particular node will zoom in on that node and the links of that node (can be the be just a reload of page pointing to a differnet xml datasource) - Every node will have different icon (also to handle the status of the node "up" or "down) - Also you need be able to click on a node and popup the short description (html iframe) (also coming from the xml) - Also you need be able to search for a node name and zoom-in it - Also need to have a list view of the nodes and be able to sort / filter by a parameter (status or location) coming from the xml This interface will have an upgrade.. which will be a different project.
