Hi Jeff, I believe that there is still a file called /etc/apt/sources.list.bak created by apt-spy; at least I have it on my system (sid with apt-spy 3.1-16).
Fort the remainder I think you're by suggesting something like a tempfile in which all new source lines are written and only copied over (or appended) to sources.list (after a backup) if apt-spy was successful.
