Please add WebDav and SSH support

Opus already supports SSH. (Requires the "Advanced FTP" optional extra. When you bought Opus it should have been offered by the web page. You can add it subsequently via the online Licence Manager.)

This thread about WebDav has something which may be worth trying (though I don't know if it works as nobody in the thread seemed bothered to try it). If you want Opus to support WebDav by itself then you should send GPSoftware a feature request (or try to convince someone to write a plugin; I'd be happy to help them but don't have the free time to write such a plugin myself).
