You'd just use a reflection shader that uses a cubemap, simple...
If you wanted realtime reflections, then you'd just update the 3 visible sides of the cubemap with a view.
NOTE: 3 Additional views will make a big framerate impact though. Make sure you adjust the quality of the views rendering to optimize performance.
NOTE #2: If anyone is interested, I'd be willing to make it (for ca$h, since my time is low, and my wallet empty

)
