It will be a interesting perspective as it becomes more common to eat insects in Western countries. The main barrier to break down would be the 'ick/ew' factor, which has been mentioned in this threads comments, that is usually cultural.
But judging from the way some domestic animals are treated by some farms, the ick/ew factor of eating insects becomes less of a barrier.
