At the moment we digitise our sections using false coordinates, then use composer to show both the plan and section views. We cheat by storing the 2D plan coordinates in real space so they show up in spatial queries and can be visualised by setting a buffer around them, but they're not really linked in a data or ui sense. Longer term, I have a cunning plan to start using the new-ish 3D geometry engine to store the sections in 3D so they can live in the same shapefiles and so be properly queried, and by clicking on the section line in plan view a pop-up window shows the section by flipping the y and z coordinates on the fly. Unfortunately it's on a very long list of such ideas... There's also a plugin called Midvatten which does borehole data which may have some ideas you could borrow.
