At my financial services company each department has a separate VLAN and 
subnet and only authorized PCs are given an IP in the range that is 
allowed between certain subnets.

By default all PCs can see the server network, but few if any PCs can 
see other HR or Accounting PCs.

In addition, it would be pretty easy to implement an IPS between 
networks provided you had gig ports and a gig IPS.
