KioFuse is a FUSE daemon to access KIO URLs. This is only the backend that mounts actual KIO URLs at local paths.
What is also needed is infrastructure and ideas how this should be integrated into KIO and especially Dolphin.
For example, the user clicks on a Networks link for ftp://blabla.com/. Other file managers already mount FUSE at this step, because they cannot access the URL otherwise. But this works fine in Dolphin, and we should not change it to go through FUSE. At this point, no FUSE connection is needed.
We need to find a good workflow for manual mounting, and investigate what can be done to do automatic mounting.
As far as I know, gvfs exposes a D-Bus API, so that it should even be possible to mount shares to local paths from Dolphin, if the user has gvfs installed, without linking to any GLib dependencies.
This tasks collects sub-tasks to handle before bug 75324 can be considered resolved.
