Use three servers. One view-server where you just consolidate everything
and two pollers. On the two pollers you just split configuration so that
each handle their own data-center.

Merlin is well suited for this, and it'll do the config-splitting and
syncing on its own. You'll find the code for it at
http://git.op5.org/git/?p=nagios/merlin.git;a=summary and some more info
at http://www.op5.org/community/plugin-inventory/op5-projects/merlin

Hope you like it. Just don't follow the ages-old download link from the
project page. I'll make sure to update it in a while, but use the tarball
link from the gitweb page for now.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
