Quote - Well, I've come to the conclusion that it is virtually impossible to have glass reflection. Not without trickery, anyway :)

No trickery involved :) Here is a test that I just did to illustrate it. There is just one top mesh light and the BG outside the window is a simple plane with a texture. The BG has been turned to a light. From the camera angle you should see how it works. Of course different angles will produce different resutls.

The reflection color for the glass is pure white, the IOR is 1.8.

 

Hope this helps.
