Here's what I did for a customer's Paramount Tandem. 105 braze on FD + adaptor for using BO derailleurs on non-BO frames + spacer made from 3/8" aluminum http://bikesmithdesign.com/temp/PaulM1.jpg http://bikesmithdesign.com/temp/PaulM2.jpg http://bikesmithdesign.com/temp/PaulM3.jpg Simple to make if you have a drill press and a belt sander. Without 'em, not so much.

Because the angle between the seat stay and seat post is more open than normal, a 20t spread uses up all the derailleur's capacity. Would be a more complicated piece, but not tricky to make, to compensate for this.
