I've learned a lot. I haven't enjoyed all of it. Whoever decided that UTP wires should be so small, and with these meaty hands I've got, it's decidedly less than fun creating the normal network ends that we're all used to. Definitely not something I could do every day.
(That said, if you're serious, it's something that I've been considering adding to the Mavelous Web Design repertoire. Any way to make a buck when you're in business, right AAX?)
