Would you modify vimrc at all on a remote server if you had to do some Python coding there? I mean maybe a few hours of coding, but you won't be coding again on that server, so you don't want to spend too much time configuring it.
Haven't been in that situation, but looking through my vimrc, the only things that I think I'd consider updating are turning off line wrap and changing the tab settings.
Basically this block:
set ts=3
set expandtab
set sw=3
set nosmartindent
set nowrap
I don't know what all of those mean, but I like how my vim works. Usually if I'm editing files on a server its just editing configuration files, and I just use whatever the stock vim settings are.
