You might have something there--make a unicycle more like a pogo stick
for hopping. It seems to me you could get more height to your bounces this
way.
Other considerations:
On the rebound, the seat post travel would have to be arrested abruptly
by some sort of mechanical stop so you could grab the seat and pull the uni
up with you.
There would have to be some way to keep the seat post (and the seat) from
turning in relation to the wheel, like oleo struts on airplane landing gear.
Some sort of preload adjustment for the spring.
