The reason the team didn't proceed is because of personel issues among the team which had they planned better would have no been an issue.
So how's this not a startup? All that would have needed to happen to make it a legal "business" are some documents signed by everyone (which were already prepared)
It costs nearly $1000 a participant, so I think $200 is actually a good deal...especially when other hackathons charge $100 but are no where near the same experience.
So yes, you can pull something complex off...but the trick understanding that seeing is believing :) A good design with grease monkey scripts to give perceived functionality that gets validation from investors is smarter than putting your head down for two years and then reaching out to the market.
