I certainly understand the concern, but I think the timeframe of this contest will serve to mitigate the problem. Three months is, in my opinion, long enough for a motivated participant to come up with an entry that could easily compete with a multi-year project.

Additionally, the openness encouraged by the competition (as a judging criteria) will allow the community time to scrutinize entries and call out any that appear to be 'cheating'.
