It occured to me that maybe I could charge my iPod off of one of the firewire ports on my LaCie Pocketdrive while it's connected to my PC at work through it's USB2 connection. I tried it out and it works.
I wouldn't have expected the firewire ports to have power. You can't listen to it and charge it at the same time though but it could be handy to know if you get caught short and have access to one.
