I'm with you on wishing WebDAV continued its rollout. These days there are great low-drama server-side deployments like https://github.com/sigoden/dufs. It's run relative too - you could habe multiple dufs processes serving up different directories in different ways. But for WebDAV, you can't simply mount that on the client side for every OS that's equally low configutaion. For that reason, I really like sshfs as it can be initiated from the client-side without a lot of config (just a mkdir of the mapped dir), and it's OK most time despite it's lack of speed and multi-day uptime. I'm on a chromebook now and it turns out that Samba is the easiest client-side tech to use for remote file systems. DAv should've been uniquitous.
