Okay, after moving and finally getting some freetime, I've decided to spend an hour of my afternoon working on this concept, and I've come up with the following ratings system. Let me know what you think of this, and if it works, I'll get the wheels in motion for actually implementing it and we can get the icons done:
Each age is, simply enough, represented by the age symbol. The age ranges we'd include would be Under 4, 4+, 10+, 13+, 17+, and Adult. 17+ can buy Adult games, but the Adult rating is used merely to identify the product as particularly "grown up" in terms of content.
Next, we use a hybrid of Van's idea and display a single icon representing the worst content in the game.
Thirdly, we use Jeku's idea and put up a webpage for each game with a full description of the game's rating, including comments by the game's submission developer AND the ratings official who scored the product.
All ratings will be treated based on a first-come, first-served basis. You can expedite your rating by paying a small self-rating fee (this will be a figure that we vote to deem as fair for indie studios). If you do this, you can place a self-rated logo on your game, but if after we test your game we decide on a different rating, your previous rating will be void and it must be changed within an alotted period of time.
All ratings can be appealed to our e-board. In the event of an appeal, the e-board itself will playtest the game and give it a rating. Appealing a rating would be cause for us to charge a small appeal fee.
All of these services (unless otherwise stated) would be free of charge for all indie game studios. The ratings board would only experience monetary gain when (A) a studio pays for self-rating, (B) a rating is appealed, or (c) a person or party donates funds to our cause. Donations would be welcome and encouraged (for the sake of the ratings official who tested the game), but by no means mandatory.
