Emacs already has exactly this built in with follow-mode. http://www.gnu.org/software/emacs/manual/html_node/emacs/Follow-Mode.html http://www.gnu.org/software

    Are you sure it's equivalent to follow-mode, not just vertical splits? Follow-mode emulates the file wrapping to the next column when it reaches the end of a buffer, and if the cursor moves across the top/bottom boundary it'll appear on the other buffer instead of scrolling the current buffer. And the buffers are synchronised as a single "page". edit: apparently you can do that with scrollbind.
