Also, would someone please tell the European manufacturers that fitting a dynohub to a pedelec is a bit mental?

Legal requirement in Germany (and probably the Netherlands), AIUI.

You could probably argue that a regenerative hub motor was a dynamo for those purposes, if you could arrange the system so the lights would work without battery power.
Careful, Kim. Your sarcasm's showing...

Makes sense if you consider that the bike can be pedalled at night with a flat battery.

Electronic shifting on hub gears?  i wouldn't touch it with a barge pole but they must think someone would buy it
Well, relying on a steel cable and a (return)spring is not always more precise and fail-save than an electronic actuator.

I don't quite understand what they are doing here.  Hub gears == no maintenance.
Although I'm riding gearhubs only in bad weather conditions, I must disagree. They require very little maintenance, compared to derailleur gears, that much is true.

I'm well too tight to give it a try yet, but it sounds very interesting.

And if I'm understanding the system right, a tinkerer like me may very well replace the cables and battery with some replacement stuff, eg. a canon camcorder battery. (?)

In this context, is there anybody to verify whether the MU-Unit would work on a normal 8- or 11-gear hub?

The issue is primarily with drop shifters. The Versa made (not Shimano) shifters that work depend on a vulnerable micro adjuster on the body of the shifter. As a consequence, they regularly go out of adjustment (I've taken to adjusting mine every day) I suspect the inevitable riding out of adjustment causes an inordinate amount of wear - when I strip mine as I will have to, the extent will become known. An electronic shift allows the drop shifter to change gear accurately.
