The insulation for CAT5 and RJ45 is rated for 125V. You don't want to be that close to the rating for a cable that can be moved/bent/stretched (for comparison, an AC cable is rated at least 300V). And the RJ45 connectors are not designed for that kind of dangerous voltage.

Right, there will be a voltage where the pins will arc, and a lower potential where a dirty connector will arc. We rented an office that had previously housed some sort of telecom equipment, so the whole place was wired for, I believe it's 40 volts rackmount equipment. That runs at lower current (thus watts) than computers and so we had to run new electrical and AC into the server room to use it for IT equipment. Cars are trying to switch to 48V because 40-50V is a range where touching a live wire gets your attention but won't do too much permanent damage (eg kill you). Or if you went with 20v you might be able to reuse equipment designed for USB power supplies.
