Monitor 40.000 hosts

Hi,
we want to monitor 40.000 hosts (routers/switches) via snmp, 5, 6 checks per host (=200.000 services to check)...
Proffesional solutions, like IBM ITM for sure can handle that task, but I wonder if Nagios (core + DNX) could to?... What do you think?
What is largest Nagios installation you ever meet?

The largest installation I've worked on is my current one of only ~7,000 hosts on Nagios XI (Replacing IBM as well actually) though I know there are much larger out there... the biggest I have heard of is a Nagios Core install running ~18,000 hosts with I think 2 or 3 servers and DNX. Would it scale that far? I have no idea... but it would be awesome to find out!

Daniel Wittenberg I believe would say yes...
See the Nagios World Conference Presentations
Scaling Nagios At A Giant Insurance Company where he goes over the steps they took to scale Nagios to 1.4 million service checks...
For whatever reason the first slide doesn't load but the rest are there..

I've also heard of an install with over 3 million services. They didn't use the front-end at all because it was just too much data, but they used the monitoring engine underneath and forwarded information up to their own in-house visualization for the data.
