How well do any of these tools work when the hosts are widely distributed or 
distributed with groups in different locations?  And how do they handle IP 
assignment on multiple NICs?  Do you need DHCP capability on all segments or do 
you need to know all the MAC addresses and the cable connectivity starting out?

Also, do they provide a version-controlled history with a way to easily find 
when a change was made and undo it?
