The Windows agent is called nsclient++. As JLC pointed out, you configure Nagios to use passive services when collecting that data.
I use it on many Windows boxes behind firewalls with great success. I've even managed to write a few custom plugins for things like NTBACKUP, ValultLogix, Oracle and the like. Nagios plugins are very simple to put together so you can monitor almost anything. As a client up sell, offer them active monitoring by putting a Nagios appliance on site that sends it's results back to your main Nagios box. This is called Distributed Monitoring.
