Is there anybody with WebDAV experience?

My webhost supports WebDAV for online storage. I want to be able to use that in my distribution workflow. Problem is that the storage folders are not publicly accessible. Of course I can pipe everything through my web-app. But that will add to my bandwidth of Xojo-Cloud drastically. Video-files can be rather large.

But first things first… how hard is it to access a WebDAV service from a Xojo web-app?
