> And don't forget daylight savings, the idea from hell.
Ahh... someone who agrees with me. Fortunately, I live in a rare place where we _don't_ adjust the clocks twice a year. Of course, I'm always trying to remember if Alberta is an hour behind us or the same as us. (If everyone else would see the light, I wouldn't have this problem.)
Ummm... isn't cat5 an ungrounded differential signal? (Yes, it is... that was a rhetorical question, if you didn't catch that.) How could I get a ground loop on it when I'm not using ground as a signal path? 10base2 on the other hand _would_ be a problem.
Well, I don't know about Joe Blow, but maybe he produces videos on a Nonlinear Digital Editting System. Did you know that uncompressed video runs about 15MB/second? Suddenly 216GB doesn't seem so huge when you can only store 4 hours of footage on it. (We currently struggle with arrays of 18GB drives, and we are constantly backing up one project to tape to do a different project.) 216GB would be _very_ useful.
Seeing as you're the sysadmin, and out of curiosity, and to respond to Jack's 'damn few' comment, would it be possible to get a breakdown of what OSes have read the article at andover?
A ground loop happens, as you say, when there is more than one path to ground. What you miss is the fact that if you lift one of those paths, there is still a path to ground. Granted... I wouldn't want 15A to ground through a thin RCA cable, but in a live audio situation (what I do), I usually have on the order of 24 XLR cables (a snake) running from my mixer. There's a lot of shield (ground) on that snake. I'm not too worried about lifting the ground on my FOH gear if it fixes the hum. Of course, getting all power from a common distro is a better solution, and leaves everything grounded through the 'proper' channels.

Notice all the different TLDs they offer registration for... They just got the .com/org/net/edu stuff now... maybe they've had the others for a while.
