Re: Fw: OneDrive backend

[Ondrej Holy <oholy redhat com>]

Hi Vilem,

thanks for your update. It is appreciated that somebody is working on
this. It would be definitely nice to merge your fork back to the
original project. Though I would still prefer the WebDAV-based
solution as it would be definitely easier for maintenance, see
https://gitlab.gnome.org/GNOME/gvfs/issues/273. Rishi should be the
right person for your questions, so I am adding him in CC.

Regards

Ondrej
