AD has been discussed before but I'm curious if anyone has thought of extracting the resources and then reverse-engineering the behaviors of the originals.
Reverse engineer them to do what? They can be used up to 9.2.2 as one of the programmers was nice enough to update it for us (Mac community). If you mean for OS X there were a couple made for OS X to mimic some of the modules.
LOL. I want to use those good ol' AD modules on OS X. They had a certain creativity and "fun" to them that still hasn't been matched. If it's possible to extract resources from them, in theory it should be possible to do.
