I dont think it would be easy but I dont think its impossible either. We have the internet which allow people to get tons of info in a matter of seconds. There are people who launch careers off the internet with out deep pockets. I havent even mention "word of mouth" advertising so it can be done. And at the very least its worth a try.
I think its this lay down and take it mindset that keeps us from the game we want! Im sure there are enough people who fell the same way most people do in OS to make them respect us.
