I think Display Target Mode only worked with Thunderbolt, which was different. I just used Firewire (er... maybe IEEE-1394, since it was in PC space) as a temporary and fast network connection for running (eg) IP stuff and file transfers with SMB, but it could have been used permanently. At the time, plugging a Firewire cable in betwixt two Windows machines generated this network automatically, with RFC 3330 addresses for each end. It just worked; each machine could be addressed by name nearly instantly after connection, and whatever file shares they had available could then be accessed with the same mechanisms that would be used on the normal Ethernet LAN. I never did anything particularly complex with it.
