Here is what the back of the side loading envelope will look like, colors are negotiable.  The shape of the opening flap reflects the over all shape of the logo, I think it gives the opening flap an interesting twist, don't you?  I also added the little play arrow from the business card to serve as sort of a "Pull in this direction" type thing.  The contact information you see is another option if the window doesn't fly.
