Furthermore, you are somewhat able to look at the code. We're not distributing, so it's legal.
You're distributing: if someone go on your server, he download your pk3.
There is patch on pk3, it's legal, but you're distributing.
At the very least, this has meant that the aimbot developer that had the nuts to come to MGDev and ask me where he could get the code for testing his latest version went home empty handed.
I don't really understand. If you are afraid for aimbot, why do you contribute to a free game ? It's easy to program an aimbot on it, and there is no good way to counter aimbots. More over, compatible aimbot under 1.1 will be easly compatible with MGDev, and the patch will probably be enough to fix little changes to make.
But patch is not enough for over developpers to re-use your modifications.
We are interested in joining the MGDev team. Would it be possible to arrange that?
If you read opinion of major part of the team Amanieu, we are not interested in joining MGDev team, but to contribute on it and work together

In fact, we manage a développement like MGDev, with the help with french and italian community. We try gameplay rules, set it on servers (european servers like cygg.fr or thcteam.org) and wait community feedback. Then, we make modifications on gameplay rules with their feedbacks.
I talked to Lakitu and other MG members about zone buildpoints, it is one of things we made.
We also plane projects like VOIP implementation in tremulous client, lua script for some callbacks (to make scenarios) and config, log rewrite to make it more easy to parse, rewrite admin system with merging / and ! commands (and make custom commands with lua configs), and we have some other ideas.
With have about 7 developpers in the team, and we are active. I think it's useless to MG and DnC to work on *same* things because a team or the other don't want to share their stuff (or don't give a way to get it easly, it's impossible to analyse a 6000 lines patch each time someone need a feature), so if we can get your gameplay features easly, you will probably retreive faster features we plane.
If a feature I descrive upper have any interest to your mod, we agree with the idea to make it as a priority, just say what you need. In any case, our svn has anonymous read access, our task list is free and you don't need a registration to post on it, our ML is free to register too, but we will be very hapiness if sharing could be done in two directions.
Friendly,
