Thanks, this is a bit clearer. I would go even further into "for-dummies" territory, such as:

How does synchronization via WebDAV work?

Synchronization involves two avenues of communication:

1. Between Emacs org-mode and the remotely-accessible share. This line of communication is used for org-mobile-push (C-c C-x RET p) and org-mobile-pull (C-c C-x RET g).

2. Between the remotely-accessible share and the mobile device(s), used when synchronizing MobileOrg on a phone or tablet.

#1 is done one way and one way only: org-mode reads or writes files to a filesystem path. When using Dropbox or Ubuntu One, it is a local directory. The Dropbox or Ubuntu One sync daemon takes care of transferring the data to the remote share. In that case, org-mode does not have to concern itself at all with the cloud storage.

With WebDAV, there are two possibilities:

- The WebDAV server is running on the same machine where org-mode is being used. This can simplify the configuration, but may restrict sync to a local wi-fi network. In this scenario, set org-mobile-directory to the physical path on the local machine housing the WebDAV share.

- Or, the WebDAV server is located on a different machine that is accessible by HTTP from anywhere in the Internet. It may be possible to mount the remote directory locally; if so, org-mobile-directory should be the mounted location. If this is not possible, you can also use scp (secure-copy) to push data and tramp to pull. Both require ssh access to the remote machine. Here, org-mobile directory should look like this:

"/scpc:user@remote.host:org/webdav/"

... where "user" is the ssh username on the remote machine and "remote.host" is the domain name. The physical path to the WebDAV share should follow the colon; it may be different from this example.

Org-mode never uses WebDAV to push or pull data. Do not configure org-mobile-directory with the HTTP URL of the WebDAV share.

#2, communication between the share and the mobile devices, does use WebDAV. Configure MobileOrg with the full URL pointing to the index.org file, e.g., http://a.webdav.server.com/webdav/my_user/mobileorg/index.org.
