Hi Michael,

I wrote a bash script that manages davfs2 and encfs for uploading the
data to the cloud with WebDAV. See for details
https://github.com/deusmax/cloud-davfs-encfs.

I have tested the package only with nextcloud, but the whole setup seems
to be generic webdav. Should work with other cloud providers that
support webdav.

Tramp uses the GOA library. I don't know if this is plus or a minus
compared to davfs2. I should look into supporting GOA, anyway.

I would be happy to port it to Tramp. You think it may work ?
Can someone give me a pointer to start ?

This work could result into creating connection methods like "davs-enc"
or "nextcloud-enc".
