launchd - running a command on every network up

    Due to having the worlds most insane network setup - work VPN at home, etc - my DNS server is under the 169.254.x.x range, which Bonjour sets up a link local route to, which has to be deleted every time the network is brought up on Tiger - be it booting the machine or resuming from sleep mode. On my Windows machine, deleting Bonjour was a possibility (and has been done), but on Tiger, this isn't possible

    I'd like to have the "Open Terminal, su, route delete 169.254.0.0/16" task I have to do every time automated, and I believe that launchd can probably be made does this for me; but I'm not sure. Screwing with network routes needs root access, which could be problematic.

    Anyone got any suggestions? I spent some time trying to see could it be done through launchd's xinetd style modes, but can't see anything obvious.

    If theres no way to get a command run on each network up, cron'ing it to run every 2 minutes or so might be a possibility if a little wasteful.
