I can't stop cracking up watching these videos. It's like a 3D visualization of Reddit or 4chan. "...in the last test players were killed 223,704 times, averaging out at 1.29 untimely ends per second."
You can tell there are pretty often some weird syncing errors, but hey, it's worth it for stuff like this.
About that 1800 players number. Based on posts by one of the developers, their server doesn't do any sort of calculation: > Our server is basically 'dumb', it doesn't do anything in the sorts of processing bullet trajectory, player line of sight or any hit detection at all. http://www.jc-mp.com/forums/index.php/topic,638.msg4783.html...

Watching that video, I would guess the environment isn't so much competitive (even single player JC2 is very no-particular-goals-in-mind-just-blow-shit-up oriented) as it is mass chaos. It looked like what would happen if /b/ bought an island. So cheating is probably only a minor concern at this point.
Would be great to see some articles on their technical approach, I assume they have used techniques to reach those scales based upon the fact the average pair of players are too far away from each other to be visible
i second that, immediately went to check if the source code is available, but sadly nothing.

They could verify those things on other clients, instead of on the server. I think that's typical for pure P2P multiplayer games. They could use something like - every player sending their version of 'what happened' to the server which then decides the proper outcome. Btw, is it required to simulate everything on the server side? I know it is the conventional way to prevent cheating, but how about just randomly sampl…
But clients are not trustworthy. How do you decide which clients to trust? How long before your 'adversary' discovers your trust methods an replicates them in his client?
"...server which then decides the proper outcome."
This requires processing power. Random sampling is perhaps a possible solution, but if you're overwhelmed with nefarious client activity (50% perhaps) and you're only sampling, say, 10%, still 40% of your gameplay is cheating clients. If you increase your sampling based on finding increases in cheating, you start to overwhelm your server farm.
tl;dr - this is not an easy problem to solve

Maybe clients could also verify each other. There has been some thought on this topic, but I don't how far the research went.
Earlier quoted context omitted.

It seems hard to general to get your hands on any modding code. Apparently the modding culture doesn't encourage opensource as much as other hacking circles.

This one's particularly great: http://youtu.be/1-zhdU4GSBA You can tell there are pretty often some weird syncing errors, but hey, it's worth it for stuff like this.
There are still plenty of funny movement related issues because of latency, but they don't really affect the game too much.
And it's totally worth it. I sat there laughing for a good long while after someone dumped a jet right into the ground, taking at least 5 people with him.
Impressive work by the developers - even though they've effectively piggy-backed onto an existing game, presumably the engine etc is closed-source and therefore their efforts are worthy of admiration.
I wonder if Multi Theft Auto is still going, I still have my Vice City disc somewhere...
