RE: [hobbit] Agentless clients

What if you were to use ssh and xargs to collect the same client
information and then just send that message straight into the hobbit
listener?  Would that work?

You can easily combine 1) and 2). Running something like this on the 
client-polling server would do it:

CLIENT="www.foo.com"
CLIENTOS="linux"
echo "client $CLIENT.$CLIENTOS" >/tmp/msg-$CLIENT.txt
ssh $CLIENT < ~$BBHOME/bin/hobbitclient-$CLIENTOS.sh
>>/tmp/msg-$CLIENT.txt
$BB $BBDISP "@" </tmp/msg-$CLIENT.txt

would run the normal client-side scripts without having them installed
on each client box, and send the output to the Hobbit server in a normal
"client" message. There is an issue with the OS'es that need special
tools 
installed (usually to collect the memory statistics), but that can be
worked 
around.
