There's a new company developing a power meter that fits between the pedal and the crank arm. They're called IQ2 (iq squared? or something like that). Saw an add on facebook, they are launching a kickstarter tomorrow.
Looks interesting here's the website. It looks to sit neatly along the crank arm will be interesting if it works on Campagnolo carbon cranks. I've not had chance to read the specifics.

At the moment it doesn't really exists. Dcrainmaker wrote a mini-preview and the company says they actually haven't been able to transmit power to a computer so far. And the fact that the powermeter adds 16mm of q-factor per side, which is a LOT (more than enough to affect your knee tracking in roadbikes)makes it not interesting for me.
16mm? I think you mean 1.6mm. The current Keos have a factor of 53mm, and DC is quoting SRM at 54.6.
Quoting Dcrainmaker: "At this point you’ll notice the obvious: The entire setup has bumped out your pedals away from the crank arm. It’s done that 16mm on each side. In most cycling circles, that’d be considered ‘a crapton’."
The current keos have a factor of 53mm as you pointed out correctly. But they are actually different ways of measuring. The keos, and the SRM are measured in different fashion. They measure from the center of the pedal to the beginning of the screw. And IQ2, is just an addon between the pedal and the crank which adds 1,6cm (16mm) to the pedal spindle on each side. A deal breaker. Check it in the attached files.
And yes, they will sell shorter spindles. But, why?? Imho if a PM is not minimally invasive it's not worth buying. I rather spend money on a reliable, tested, and closed system instead of adding more variables than needed and will certainly affect precision. At the moment it doesn't work, they have just strain gauges with a very low tolerance.
