Looks OK. I think you need to look at the next level of link management:
* Ability to discover/spider the network and auto add devices (huge)
* Ability to change links and “save changes to network”
* When you do link management at the device level, should be able to see/edit all controllers and responders to the device
I realize you guys have a ways to go with this. One final suggestion, does it make sense to try to integrate java or something like that. This would provide the abilty to use trees rather than dropdown boxes for thinks like areas, etc. which would be useful from a control perspective.
