No, it doesn't have a hub brake. I think the full Rohloff assembly is around 
200 g heavier than an equivalent derailleur set up, which doesn't sound much, 
but obviously more weight would be concentrated in the hub.

I think it's an excellent idea - the rohloff doesn't have hubbrake, does it?

The weight of the hub can't be significantly higher than dual chain wheels, 8-9 
speed casette, front and rear derailleurs, extra chain length and so forth. An 
adjustable framelink are great, but not so much because of the gearing system.
