Today, AnthraX released the first public version of the new anticheat ACE.
ACE is a new anticheat and in the community considered to be a replacement for UTDC, which doesn't work properly on newer (64 bits) version of Windows. More information is available
here.
I expect troubles with this beta version and necessary features are not implemented until at least version 0.7. And we have a version of UTDC running in compatibilty mode, allowing most players to play without (serious) trouble.
Because of that, we don't have an urgent need of installing ACE on the server at this moment.
