Cisco has an interesting innovation competition on-going - I-Price [1].
Cisco's CEO is inviting  all interested people to participate their innovation competition.
The winning team has an opportunity to be hired by Cisco, and get funding for their new business idea.
Cisco will be investing ~ $ 10 over three years to develop, staff and go to market with the selected idea.
There were over 1 000 ideas suggested in the first stage.
Cisco's innovation blog [2]keeps people posted how competition proceeds.
 
Good example of crowdsourcing.
