Unfortunately I am not familiar with this mod.

One thing to keep in mind is a lot of mods were frowned upon or flat out not allow at all, especially as you can imagine with playing competitive. Once PunkBuster did finally get release for Q3, there was also a bit of hesitation from ranked players on making any non-typical modifications to the game out of fear of being banned. That said, aimbot was a huge issue with Q3 and rarely did I witness PunkBuster do its job.

iD tends to be very tight lipped about things from my limited interactions with them, even in person at Quake Cons..but I do know they were all hanging out on the same forums and places the players were at - so my hunch is they were aware of it.

I mostly lived in modded Q3A - held a few world records in DeFRaG from time to time, but none that were important. I miss those days, they were the best of times :D
