We're monitoring around 1000 hosts and 4700 services. We are using the last version of Opsview Community like Simon although his setup sounds a bit more fault tolerant.
We have 1 master server with about 30 slave servers monitoring various remote sites. Easy of distributed setup was what won us over to Opsview several years ago but as they moved the distributed version to the enterprise commercial edition I am starting to pay attention again to the different variants of Nagios out there. Also centralized web based configuration front end was another huge plus as engineers don't have to understand Nagios to setup hosts. The racoon setup sounds like some good stuff.

Impressive :) We're monitoring ~2000 hosts and ~10000 services, every 5 minutes. Architecture used: OPSView Community edition, the last free version before it started to make the distributed version commercial :/ Two central servers (active/standby - drbd) as single point for management and collecting all passive checks executed by the slave servers. Performance data saved into rrd files as well on an external BIG database server. Configuration resides on a cluster MySQL installation (drbd). 4 slave "datacenter installations" with 2 servers per "datacenter" in active/active load balancing. Traps handling supported on all servers with rules logic. Pros: - Open Source: at least until version 3 - for our setup. Simple single instance with fewer functions available as well on version 4. - Easy to manage: the prupose was to create monitoring system and then let the management to other people with less technical skills - distributed setup - RBAC Disadvantages: - no longer Open Source: see above - Central server suffering on cpu by GUI implementation and other bg jobs - Not all nagios parameters editable as we like: i.e. cannot customize same checks with different intervals without having to re-create new ones. Think on HTTP service on servers with different loads and the need to extend the retries on high load servers. no way expect creating "HTTP" and "HTTP High Load" services. Maybe there are more pros (and disadvantages), but it's not the right place. BTW I'll look forward to wait for this solution; seems interesting!
