It may be too expensive, but we're using a switch/router that gives us 48 ports for < $5K US. It priced out much lower than most chassis-based units, and it has some nifty features. You can give a "master" vlan an IP, say a /24 and include other ports as "sub-vlans". Each of these can be bound to a port and either a range of IPs or a single IP. It locks people down pretty hard, and if they try to nab someone else's IP, they simply drop out of the vlan. There's really no need to do MAC-level locking, as everything happens at the IP layer. You can also flip a switch to prevent users from even exchanging traffic with each other... Very nifty, but maybe out of your price range, I don't know.
