Hi Paul, with a Python, the coasterbreak is in the frontwheel anyway. It is also a lot more efficient as on a RWD bike.

Also nice because now the back-pedaling coaster brake can be attached to a front wheel brake which is more effective at stopping the bike. The only problem I foresee is that it would be easy to break the cable with too much force applied to the brake. Perhaps spring-loading the cable so that a firm pressure may be applied after which the back pedaling motion hits a stop.
