aluigi, can you explain how q3dirtrav works, or can you link to a patch against the q3 client?

what is the patch about you refer?
the q3dirtrav can be removed setting sv_allowdownload to 0 and if you can't or don't want to disable downloads I created a patch for the bug for the Windows executables called q3dirtravfix:

is there a diff of the source of the bug fix? I'm talking about a 'patch -p0 <' patch

the q3dirtravfix patcher is open source but naturally doesn't exist a "diff" because the patch is dynamic and the code auto adapt it to the target executable (because it's almost universal for any windows executable of game based on the quake 3 engine).

the only way to make that diff is taking the original executable and the one patched by q3dirtravfix and then getting the differences with patch or other tools.
