FWIW I experimented with dinglespeed on a road frame with horizontal dropouts. I used a road chainset and two cogs on a road wheel. I choose my rings and cogs carefully to give me 66 and 50 gear inches with the same axle position in the dropouts. I used a QR on the rear wheel and got pretty handy and switching gears beside the road in a matter of seconds. Avoiding oily hands was the trickiest bit!
It's great if you want a simple bike for riding to, up and down mountains, but not much else.
