You should also check out Shifter (if you haven't already). The latest versions fix a number of the AI bugs previously present in the unreal scripts, adding better detection of stealth, better aiming, enemies actually using items, etc. There's also another project that fixes even more of the AI bugs, making them much more aggressive, as well as smarter about finding you. It's based on shifter. Wish I could remember the name of it, but if you're interested, I suggest looking around on the internet for a bit.

HDTP fixes a lot of the models to look considerably better.

Also, check out Deus Ex: New Vision. It's a complement to the HDTP project.

Some of us did exactly that. Others started playing WoW.

I was thinking it was a gateway bug

We have them, but they're mostly just ignored. I think the reason we're no longer using the cameras is that the expenses for mailing all the tickets outweighed how much money would actually be paid.

Getting them or trying to protect us from them?

It's only possible because these "Linux" guys took a lot of the code they're using from an existing company named SCO.
