I have an Airport Extreme. If I plug a hard drive into it, is there some way I can access those files outside of my network over HTTP for things like sharing files with clients? The "Share Disks Over WAN" option doesn't seem to do this. I know the AE seems to run NetBSD, so maybe there's some hack to get Apache up and running on it? Currently I just host the files on my Mac, and that's fine, but it would just be cool if I could do this directly from the Airport.
