MasterChief58545,
Halo Custom Edition allows for the creation and use of custom maps. It also introduces altered netcode and improved shader performance, which on average has increased the framrates for a lot of players out there. It is a stand-alone, multiplayer-only version of Halo for PC. You can have both versions of Halo installed at the same time or just Halo Custom Edition; your choice.
As for your second question: No, you cannot use this without a valid CD and key, but it is free to those who have purchased Halo PC. So get on it, masterchief58545. ;) If all the people who were playing the demo today were to switch to CE, we might see some much needed updates to this game. Plus, the real version of Halo plays about 100x better than the demo. I don't know how people can continually play that horrid thing.
