I've thought of that myself a couple of times - it would be useful if
Hobbit could make use of some of the Nagios modules ("plugins", in 
Nagios speak).

But Nagios is very different from Hobbit. The network protocol used
between the Nagios server and the clients is not documented (at least,
not anywhere that Google can find for me), and it is also a "pull"
type of protocol, where the Nagios server polls all of the clients
to pick up data.

Doing a "pull" from the Hobbit server wouldn't be all that difficult,
but it would have to mimick the behaviour of the Nagios server. And
since I haven't found anything about how that works, it means digging
into the Nagios server code and trying to figure it out from there.
Or setting up a Nagios system and doing network traces. Both would
take more time than I'd like :-/
