I'd like to make a debian package that automates the installation of this and requires little-or-no per-user setup
To do that, I'll likely need to:
- See that sshfs-fuse accepts arguments to the ssh_command
- fold sudo_ssh_user into /etc/auto.ssh by finding the username in the $PWD variable
- rename the hacks file to autosshfs_ssh :)
- create and test an /etc/X11/Xsesssion.d/91x11 keychain script that overrides the 90x11 ssh-agent
- find some way to automatically mount for all users

Possible way to automatically mount for all users
- create a separate init script, possibly based on the autofs init script
- finds the list of users, and mounts autofs for each of them

Also need to clean up
- use keychain only if it's installed and an encrypted private key exists
- use the reconnect option

Dreaming
- A wizard for setting up remote ssh keys
- My own ssh password asker that handles finding a display, preferring the active vt
