I've been thinking about using code in op2 to help WD work, but can't come up with anything good (things will get easier to do with HFL though, like a random mission vol named WorldDomination.vol or something). The only problem I can't fix is getting game info to the server, since I know nothing about coding for the internet.
Edit: You might not even need a vol for it, since hacker has the recorder switch dlls to playback missions. Just a list of maps to randomly pick from within a single dll.
