[boost] asio review: are we still on topic?

Guys, This general discussion about which approach to networking is superior is very interesting (and useful for me personally), but I think we moved off topic. I think Chris (the author of asio) agreed that both approaches are valid, and claimed he gives both of them appropriate attention. So now, since I pointed to what I believe is a problem with the synchronous interface in asio (socket dependency upon the demuxer), doesn't the critique of synchronous approach sounds a little bit like: "It is inferior anyway, so it's a goot thing that it's not clean" ? Because nobody yet tried to convince me that socket dependency upon demuxer (even if for synchronous IO only) is a good thing. Regards, Arkadiy
