11.1 Gnome 2.24 Access unmounted Encrypted vol via Desktop


I have an encrypted volume which I only access from time to time.
I use 11.1 and Gnome 2.24

I want to be able to double-click on an icon on my desktop, be prompted for the password to access the filesystem and then have nautilus do it thing.

Any ideas?

I’ve experimented with a launcher to a location, and with the automounter and got nowhere.
