Fusedav is a userspace filesystem driver that allows you to mount WebDAV shares. This way you can transparently edit and manage files on a remote server.

It uses FUSE (Filesystem in USErspace), thus you need a FUSE-enabled kernel.

WebDAV (Web-based Distributed Authoring and Versioning) is a set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers.
