Working with "web hosting" is easy. Put the OpenAFS client on your web team's macintoshes and then use it to access the directories hosted on your OpenBSD web server: http://www.openafs.org/macos.html
>From there it is about the same access as having the files on your local harddrive. There are OpenAFS clients for linux too but see your distro's repository for details. Regards, -Lars
