I think that
Game Tap could be the third party company you're after; they already do a large amount of titles from a selection of systems and often acquire 'new' titles, the only problem being that it's a monthly subscription, and at no point do you actually get to 'own' the game.
So, maybe it would have been best to write to the people of GameTap and say "Is there any possibility of you ever getting game
x on your site?" and then seeing if they're open to suggestion regarding the games they add, as you say though these kinds of requests are much better coming from paying customers.
Thanks for the feedback on the entire petition, it's been a rather interesting education.
