You do know there's more to life than static IP webapp servers, right?

how about a internal media server cluster being used in a professional 
video editing environment with workstations running various sorts of 
editing software, monitors doing streaming playback and such ?   that 
world relies heavily on uPnP, BonJour, etc.

My development lab environment, most of my servers (75% VMs) are DHCP 
configured (using static and/or long lease time reservations), which 
makes doing PXE and such much easier.    A foreign DHCP server would 
quickly be detected by the corporate IDS and cut off the network.
