Wow. I work for another US government agency down the road from LBNL, and here I can't even see many internal servers from my laptop because there is a firewall between the (wired!) laptop-accessible network and the inner ring that the servers are on.

I think my sysadmin group would have a collective heart attack if they saw that setup! It's quite incredible to me how independent various parts (and pseudo parts like the national labs) are from each other.
