If it's all and correct I could add it on wiki, no problem at all!
Thanks to Simone for adding the page on the wiki:

I've made a few amendments, but the data there is accurate.
In addiction, for me it's not so transparent how (which services are
involved) on distributed monitoring, passive checks-results are sent
back from slave to master if NSCA is listen on master's localhost
port only. I've tested a pure nagios setup and the passive check
output was sent from slave to master using send_nsca and pointing to
ip port 5667 of the master.
I've updated the NSCA to say that the port 5667 is tunnelled to the
slaves. So slaves do a send_nsca -H localhost -p 5667, which is
tunnelled back up to the master. This provides encryption and
authentication, so is a secure way of transferring the data.
