Hacking Through Firewire Connection

Apparently someone just noticed that unrestricted direct write access to RAM is a feature of Firewire (according to the article). This allows one to compromise password protection code, and probably most anything else one can imagine. This is described as being done with a physical connection to the target system through a firewire port, using another system. Windows and OS X are said to be vulnerable to this.
