Exactly. Behind the utilities (closely monitored and highly restrictive) 
firewall. Most likely behind multiple firewalls. (border fw, internal 
operations fw, monitoring network firewall). No reason they shouldn't

This is no different then having machines with a public IP on the net 
today. A firewall is such a small part of an overall security architecture.
