Yep, and you can run it a good distance as well. I have been using UTP cat5e for a long time and it works great, cat3 also works. Most places that are new installs are putting cat5 into the walls and electrics to run DMX through so when the switch to ACN/any given distro protocol happens you simply rip the 5 pins off and put on ethercons or whatever we finally settle on. The only thing to be aware of is off the shelf cat5 is a fairly brittle cable. Buy cable that is specifically made to be handled often, not the 1000' boxed rolls.
