Not at the moment. These are ancient (hospital-specific) servers, which
we're not allowed to modify. Well, not allowed .... i prefer not to change

If not, you need another vrrp_instance defined which makes the default

I'll try that, and i just got another idea here: what if i spoof a mac
address (macchanger) and have it fail over to the other director (via the
notify_* scripts)? Would that work?
