i had a drum braked, planetary 3 speed hub on an old tandem back in college,
working in a bike shop yielded many treasures from the parts bin
old Sturmey Archer 3 speeds never needed any work when lubricated & left alone
Woot!:

can you say no chain slap?
if you wanted to get really obtuse you could run an idler and shift the front chain rings
there are support groups for this malaise
http://www.sheldonbrown.com/sturmey-archer.htmlAlmost all English 3-speeds have Sturmey-Archer rear hubs. They made many different models since the company started in 1903. Sturmey-Archer was a division of Raleigh Industries until autumn, 2, when the parent company ran into financial difficulties. The land the factory stood on was sold, and Sturmey-Archer was nearly liquidated by a corporate raider. Fortunately, a Taiwanese company called Sun Race came to the rescue, and bought the company assets were purchased more or less intact. The machinery and stock have been moved to Taiwan, and it is expected that Sun Race will be resuming production of Sturmey-Archer hubs once their new factory is completed.
