I wrote it up in a bit more detail[1], so I'm giving away the punch line here, but I used to use some cursed bash wrappers to smuggle my bashrc and vimrc along on ssh sessions to mostly-ephemeral hosts by stashing them in environment variables matching the LC_* pattern allowed by default for pass-through in debian-ish sshd configs.
