rsync the program is a one way transfer system.  However an important part of rsync is its file transfer algorithm, which transmits a minimum amount of information to update a file.  I intend to implement the algorithm for file transfer, not its synchronization algorithm (in fact I cannot use the rsync program itself since with ownCloud I only have access to php).

Except I have neither two push file modification, nor can webdav provide the rsync file transfer backend required (at least as far as I know).  If it can I'd use webdav for the file transfer but I still need the push notification support from my plugin.

One of Dropbox's strengths is that your folder is *always* synced with the server.  Any other type of syncing would mean that you have to run manually every so often.  And I really want to avoid very frequent polling as well.
