Automated os x macintosh password retrieval via firewire

I’ve successfully created a Python script which can extract username and login password from a mac running OS X tiger (going to test with leopard asap) via firewire using a linux laptop, based on great paper Hit By A Bus: Physical Access Attacks with Firewire by Adam Boileau. Once the attackers Linux laptop is connected to target machine via firewire, the password can be automaticly extracted from memory via firewire in about 10 seconds.
