I've used the screenshot services for desktop browsers recently, and since I believe in the coming age of offline webapps for mobile apps, I think a variant for mobile browsers could be interesting.
My main worry about setting up such a thing, apart from the general unpleasantness of dealing with crappy emulators and browser engines, would be security issues. Certainly all the emulators (or phones) have huge security holes. My admin knowledge is rather basic - are things like chroot or virtual servers sufficient to shield from such perils? Still, in the most paranoid case it would probably mean starting an extra virtual server for every rendering request, which would presumably be extremely slow. Or am I way too paranoid here?
Another thing I could imagine would be to transform every website into a passive website and only show that - but it would be complicated, and might yield incorrect results.
Would doing it with emulators even be worthwhile, or would actual devices be the only thing that makes sense?
