Lendal's Paddlok system comes to mind, though you'd have to modify 
other maker's blades to fit.  If you get a variable length version, 
then the widgets you plug into other makers' blades to adapt to the 
Lendal shaft could be accomodated.  You'd have to fabricate your own 
adapter widgets, of course - no one sells such a thing that I'm aware 
of.

Paddle rotation may be measured, but gyros aren't the way to go.  
Accelerometers only measure acceleration, not velocity, so any 
constant velocity period in the stroke would be unknown (except in 
duration).  You might be able to make it work (integration of values 
etc) but I'd have to think about it.  There were MIDI based systems 
that allowed people to "conduct" music by following thier hands 
(without touching anything) - something like that could be adapted.  

On Nick's comments:

As far as strain guages only measuring forces - you also have time 
and boat speed measures.  Something in the back of my mind tells me 
that this combo can be used to effectively deduce work, but I haven't 
worked it out.

PS - I'll be away for a few days - how come the interesting stuff on 
Paddlewise occurs when I leave??? :-)
