Good stuff. What I have taken from the whole thing is that if I add some ram I can play all five on a single PC again (it worked fine until I hit outland, then I needed a second PC). I had narrowed it down to either game-loading disk access or running out of memory and swapping being the possible bottlenecks because the disk light was on continuously. I need to get 64 bit vista though as I only have 32 bit.

Why symlink the wow dirs instead of running them all from the same directory?
