"So why would you want to use Firewire instead of Ethernet to network computers? Well, normally there wouldn't be a reason to, but because standard Firewire supports speeds four times greater than Fast Ethernet — 400 Mbps compared to 100 Mbps — using Firewire could be advantageous if you need to move large amounts of data between two computers as quickly as possible (say, to transfer data files from an old system to a new one)."

"Windows XP allows you to connect computers through their firewire adapters. Sort of like the com port connections that were commonly used in a home environment before network adapters became cheap."
