It's not (just) about asio design.

Of course it's cool but there are limitations given by the OS and the GUI 
framework you use that do not allow that to happen. Do you have on all asio 
supported platforms an OS system call that can wait for events either from 
sockets or GUI? If so then you can do it (with some modification on asio to 
allow extensibility at that level). If not then you can't do it no matter how 
you design asio.
