An open invitation: If you see me being glib and handwavy, please, ask for an elaboration. I have many faults. Insufficient desire to talk is not usually one of them.
I'll happily write up 800 words on why SaaS means piracy vanishes overnight, but the short version is just as informative: pirating the client means you can pirate the service like "pirating" Firefox lets you pirate Basecamp. Do you want me to talk about the China angle and how essentially all games in China (and Korea before it) are currently "free to play" with property/boosts/etc maintained on the server? And how that model is going to become dominant in the US, too, because gamers are voting for it with their wallets?
It's been interesting seeing how your (modest) success has turned you into an asshole - shame really.
Perhaps when accusing patio11 of being an asshole -- which I don't believe to be the case -- you could try not being a snide asshole yourself with your "(modest)" remark? Plus, even a cursory scan of his comment stream ( http://news.ycombinator.com/threads?id=patio11 ) disproves your assertion.
I see no asshole-ish nature and I'd bet it's 100% on the money, though I've never sold downloadables so I can't speak from experience.
Let's stay above name calling. We're all adults here.
