I don't think it's a pipe-dream.  You can certainly pull it off, it's just a matter of doing it for the things that matter, and making you more efficeint. If you have the ability to scan a part every time you have to make an unexpected trip to the van, then yes, it'll save you money, and make you money.  You just have to do it for the "right" parts.  And you're right, we all know what they are. Short HDMI cables, LV1's, optical patch cables, etc.  Those things definitely add up, and we all give them away.
