OP here. VimSwitch does something similar to what your script does. It just makes it a bit more convenient. Here is a use case that I plan to use it for:

    # log into production server
    $ vimswitch priomsrb/vimrc
    # -- work --
    $ vimswitch default
    $ logout

This puts vim back into it's original state for the next person who logs in.

In future versions I hope to make the above workflow even simpler:

    # log in to production server
    $ vimswitch --launch priomsrb/vimrc
    # log out

The --launch command will launch vim with your settings without altering the home directory.

If that's the symptom then I would recommend using different SSH users instead of everyone sharing the same account. It allows each user to use it's own config and also makes `who` more useful.

That's a good point. My example comes from experiences where the only available users are 'admin' or 'logs'.
