auto-detecting of new hosts, routers etc...

[Matthew Joyce]

One way would be to define the entire IP range as hosts and have a check
which checks they are not responding (unless they are authorised
devices)
If a new device come on the lan, this check would fail and send an
alert.

If you're not comfortable having the existing config altered by a
script, why not have nagios scan a folder for CFGs.
A script could add/alter individual CFGs (archive older versins), and
send you the result of a `nagios -v`, ready for you to bounce the
service.
