From a user point of view, why do you care if it has a real socket connection, or a emulated connection that does exactly the same thing? I'm not sure any user anywhere would notice the difference. There is no noticable difference in terms of latency, negligible difference in terms of bandwidth. I have thought about the possibility of using it where available, but I don't think it'd really be worth the effort and potential issues.

Fair enough for text rendering, but html is getting better font rendering also. I know which I'd put my money on. I can't even select the damn text on scribd.
