I made a simple anti-cheat client in Python, following this request:
http://forums.alliedmods.net/showthread.php?t=133812
I'm not releasing the AMXx plugin as it's trivial and shouldn't be public, since one could easily exploit the anti-cheat with access to the source code. Do your own plugin if you want to use this client.
This is not a polished product, it was a console application until a few minutes ago when I did a quick graphical interface, just to make it prettier.
You can see a video of the client in action here:

I'm providing binary versions for boring people who don't have Python installed.
The server is just an example of how to interface with the client via sockets, use it as a base to your own plugin. It will create processes.txt and screenshot.jpg in its directory after a successful run.
Downloads:
For the binary releases, just extract and run anticheat.exe or server.exe.
This is a cross-post, the original thread is here, but since the tool isn't specific to AMXx or SourceMod, I'm posting it here as well
