Coincidently, I was just trying to edit a file on the filesystem with an FTP client going thru Zope/FTP and a LocalFS. It didn't work. The LocalFS instance didn't look like a directory to FTP so FTP could neither read nor write to the directory.
Does that throw a monkey wrench into your idea?
No, not really. LocalFS was just an example. The only important thing is that I can edit something, post it over the web (either from a weg form or using FTP, WebDAV etc.) and then store it to the filesystem instead of the ZODB. BTW LocalFS works fine over the web frontend, and FTP over Zope over LocalFS is not really necessary in most cases, as you can go directly to the filesystem with plain FTP anyway. But LocalFS should be fixable to work over FTP, I think. Joachim
