Thanks Sean

I did want to physically hook the drive up and run it on both computers at the same time just to see if it would. And I did try it yesterday. Here's what happens.
When I turn the power on to the external drive connected to both computers with firewire, one computer would reconize it while the other wouldn't. If I toggled the power on / off to the drive, the other computer reconizes it and the first doesn't.
It didn't seem to affect either system.
I guess I wanted to try this because (other than I was bored

)) I wanted to see how much faster firewire / USB 2 was in data transfer as opposed to over ethernet. I still have yet to benchmark it. Although it did transfer 27GB in about 30 minutes via firewire. Later I'll transfer that over ethernet and see how long it takes.
Yes, I DO have too much time on my hands
