Nike+ & WBF Takes Over The Nation’s Capital
Smarter and cheaper Pavagym option

Check out this video and look around 1:30
Looks like this does exactly the 2 things we need to get done: tracking how many jumps, how high, and maybe sth else.  I think it’s all done with Nike +
This looks like a more flexible (space wise), cost-effective, and maybe customizable than buying Pavagym.
Nike has been doing the exact same thing for bunch of events around the world.
I’m sure we can do the same thing without Nike, those codes are probably open.
