The Hobbit client already collects "netstat -rn" as part of the client
data. You can view it via the "Client data" link from any status page,
or you can grab the latest version of it with
 ~hobbit/server/bin/bb 127.0.0.1 "clientlog HOSTNAME section=route"
The netstat-rn output is in the "route" section of the client data.

So it's something fairly obvious to implement as a server-side
extension, like the "hobbitd_rootlogin.pl" example that is
included in the current snapshot. You can grab it from
http://hobbitmon.svn.sourceforge.net/viewvc/hobbitmon/trunk/hobbitd/hobbitd_rootlogin.pl?revision=5819
