Use DenyHosts to Allow More Secure SSH Access

The FLOSS project DenyHosts is designed to make it safer to allow SSH access to hosts. The basic idea behind it is that when there are X number of unsuccessful login attempts from an IP/host it will block that host from connecting via SSH.
I used this program back in the day, under Fedora, but ran across it again today as a possible solution for a security threat I identified during my weekly audit. Not sure what platforms it will work on, but I imagine just about any *NIX based system that has Python installed will work.
