In my experience, any sort of filesystem remoting a la sshfs simply doesn't perform well enough to do real editing work in. One of the really nice things about vi is that it was originally designed for low-bandwidth situations, so using it over ssh is quite snappy even on a marginal network. If I had to use sshfs from home to edit files on my production servers I would probably have to kill myself.

I agree. I can comfortably get seconds ahead of what's displayed on my phone, when needing to fix something in an area of poor coverage. Knowing my ASCII chart can come in handy, on the limited phone keyboard, though...
