While I really see potential of asm.js couple of things about execution (including this title)

1. Brings my browser to its knees (Firefox here)

2. Security. They seem to open themselves up to a whole lot of potential hacks (I hope their code deals with cookie jacking, csrf, sniffing, etc). While this would be a problem with closed source, this is made worse by running it in browser

3. Cheaters. How would they deal with people injecting code and creating bots?

2. It's javascript running in the browser, it can't do anything that you couldn't already do with javascript running in the browser.

3. The same way that companies currently cope with clients. It's not like client-hacking isn't so common-place that you have to design around it anyway.

2: There's always the option to run the game iframed, served from a subdomain or similar.

3: Cheating has always been possible, in all games. The minified javascript source is still hard to grasp for a game that size.
