Integration of virtual folders in home directory tree?

[Volker Augustin]

Hello,

is there a way to integrate "virtual folders" in the users home directory
tree? I would like to define .desktop files containing ioslave urls like
fish://user@host/path and want to assign a folder name to those urls
and that folder name should then be shown in the normal home directory
folder tree as subfolders of the folder containing them. It should be
possible to preset a password. If no password has been set in the .desktop
file, the ioslave associated with the .desktop file should ask for the
password and then try to open the location.

Regard,
Volker Augustin
