The Dynapac hub dyno's are becoming more popular over here. There are 2 that I know of in the country, Abbey Motorsport and Thor Racing.
There are supposedly some benefits over a traditional rolling road in the elimination of slippage of the tyres on the rollers.
There is also an argument that you get very consistant results as you also eliminate the variation in tyre pressures and heat built up at the rollers.
I suppose regardless of this you still only get a figure at the hubs rather than at the wheels or the flywheel so how useful it is will be another point for endless debate.
Dyno's are primarily a tuning tool though and you would think that the consistency provided would be an advantage in setting up your car.

Additionally, all these dyno's, rolling roads etc. are only of any use when the operator actually know's what they're doing and is familiar with the engine that's being tested.
In recent years with the increased interest in vehicle tining, a lot of new dyno operations have been set up. They may be a dab hand when it comes to ECU remapping etc. but give them a good old carb to look at and you're faced with blank looks.
When mine was on Dave Walker's r/road, he readily admitted that he knew 'sod all' about SB Chevy's! Give him a MK3 Escort with EFi and he was happy as Larry

That's a very good point 
I would always choose my tuner by their results and reputation, not by the kit in their garage.
Some of the best engine people out there are still mapping / setting up cars on the road and getting amazing results.
There is also the argument that a dyno is a simulated environment and you can only truly get the car right on the road under real conditions.
