Bonus points if they go from max reverse to fwd idle in one motion.

I suggest a quick read of this incident report (AAIB 5/2012) should answer many of the questions raised.

Thanks for this. Iíve used reverse while on the taxiway after vacating. Not sure down to what speed though- I doubt as low as 15kt. Iíll certainly keep this incident in mind for the winter though.

It is related to aircraft/engine type. Iíve seen it in the MD-80, 727, 737-800, 757, 767, 777, A300, A320, A330.

Iím starting to think itís not the engines fault.

I'm not certain about other types, but it is SOP for the 737CL and NG.

IIRC ( Although it's probably forbidden by most company's SOPs) the 757 was certified for a power back but I think you need an NTO for it. I don't know about the 767.

"This thing seems a lot more sluggish than usual- oh, wait, reversers still out".

Ahem. Not that I've ever done that.

We demonstrated the capability on the 767, but it was never an approved procedure. To use it, the operator would have to make a specific request to Boeing, and Boeing would issue an NTO. I don't think it was ever actually done out in the real world. Basically for emergency use - e.g. there is a hurricane coming and you need to get the hell out of Dodge before it arrives but don't have a tug available.
I suspect the 757 was the same way but I don't know that for a fact.

Or you just do it, and hope it won't end up on Youtube!
