I recall Modo came up with a solution to this called portals I believe. From what I remember it takes light and channels it through the window openings. Anyhow, maybe something to look at?

I was thinking about portal lights also. I render and bake a lot in mental ray and portal lights on interior openings are really necesary for clean solution in reasonable time.
