funny you should say that AA, last night i went to play UT for the first time in ages, and a lot of servers was running a new protection called UTDC. when entering the server (for the first time) it wanted to install a checker locally on my machine, and when i clicked OK, it shut down UT, pretty much like LFS restarts after an update. i'm presuming that having it running locally as well as server-side it can check alot more - at least i hope it is, lol i'm no expert.
