  Why wouldn't that be possible? Each text view allows you to test focus on
the text view directly do something similar to the following for each
text_view window:

gtk_text_view_get_visible_rect (GtkTextView *text_view,
                                GdkRectangle *visible_rect);

and from that get an iter:

gtk_text_view_get_iter_location (GtkTextView *text_view,
                                 const GtkTextIter *iter,
                                 GdkRectangle *location);

  Which you can check against the current "insert" mark and iter obtained from:

GtkTextMark *
gtk_text_buffer_get_insert (GtkTextBuffer *buffer);

void
gtk_text_buffer_get_iter_at_mark (GtkTextBuffer *buffer,
                                  GtkTextIter *iter,
                                  GtkTextMark *mark);

  The text view with the "insert" mark would scroll on its own as you advance
the cursor (just as using a single text view would). I don't see any problem
switching between the views to control the split-view you are trying to create.
