Hobbit 4.2.0 does have a mode of operation where the hobbit server can poll 
the clients. This is the msgcache/pulldata method. In this mode, you enable 
the msgcache task on the client, point it at 127.0.0.1 (so it will push any 
test results to the msgcache daemon), add the 'pulldata' keyword in the 
bb-hosts file, and enable the hobbitfetch task on the server, then the 
server's hobbitfetch will connect to the msgcache on each client with the 
pulldata keyword, and pull the data that was left there.

OK, well this should all be possible. I'll try and get around to seeing if I 
can implement hobbit-client-like templates for standard unix+snmpd. However, 
note that in this case, devmon will have to manage thresholds etc (but, 
hobbit can still do alerting etc.).
