I'm just about to try an install of 2.4 - today or tomorrow. There's one little thing I'd like to be added to the configuration file caldavd.plist, and that's a key/value for the location of the mime.types file. (Forgive me if there is one already that I've overlooked.) For the minute, it seems that I have to edit the twistedcaldav/__init__.py source line which says in the original: File.contentTypes = loadMimeTypes(("/etc/apache2/mime.types", "/etc/httpd/mime.types",)) I'll put in a formal RFE if that's required.
