At that kind of scale, you need to take a serious look at moving away 
from the Nagios plugin model. Any model based primarily on forking
external processes is going to hold you back.

This kind of scale is easily achieved with OpenNMS with appropriate 
hardware and planning, largely because it does everything in-process. We 
do offer limited support for NRPE as a transitional mechanism. 
Disclosure: I get paid to work with OpenNMS in a consulting capacity.

Zabbix is open source. I know some of their team and would recommend 
putting them on your list.

I also know a number of brilliant people who work for SevOne, but I 
don't know much about their product.
