I've been a long time lurker and an avid cyclist, manage a small bike shop actually. I'm a recumbent rider, and have ridden quite a few hub motor bikes, they're great but feel a bit weight sluggish. (Thank god Lithium batteries were invented)
I recently came across this:
http://www.gizmag.com/velological-worlds-lightest-e-bike-drive/31976/
The idea doesn't seem bad except the constant need to replace the tiny rubber wheel and not sure if I want to wear down a rim's sidewalls.
That got me thinking, with many available forks that offer both a V-brake option as well as disc brake tabs, would it be possible to do something similar to the above but mount the motor instead to the disc tabs and have it run a rubber wheel friction against the disc rotor? (Using the Vbrakes as brakes)
Rotors are cheap to replace and meant to grip and dissipate heat well. I really like the small motor design and think driving the wheel at the center would also give it more torque.

My other idea was to copy the one above but instead bolt the motors directly to a pair of vbrakes as Vbrakes would already have all the adjustments and tensioning options built in.
