Basically, you just change what the view look at to just a tile rather then it following the player.

Look into client.eye in the DM reference.

mob
    var
        atom/view_source // The center of this view.
        view_distance // The distance from the view that
                      // they are allowed to move.

    Move(atom/loc)
        if(view && istype(view) && (get_dist(src, view) > view_distance)
            // If the view is set and it's an /atom, but if
            // the new location to move to is outside their
            // allowed view, block them.
            return 0

        // Otherwise, allow them to move as normal.
        return ..()

    proc
        SetView(atom/source, distance = 5)
            view_source = source
            view_distance = distance

            client.eye = source
            client.perspective = EYE_PERSPECTIVE 
            return 1

        UnsetView()
            view_source = null
            distance = null

            client.eye = src
            client.perspective = MOB_PERSPECTIVE
            return 1


This won't work for views that can move (such as if it's a mob following a path for, say, an escort mission or something). This would require you to modify the moving thing's Move() proc also, to force others to follow along.
