Thank you for your input and your interest in general.
I certainly had in mind adding sockets to GOIO.
As for GIOChannel, I doubt it's worth unifying it with
GOIO because it's too limited and suited for modest
requirements (i.e. no GObject).

Async capabilities weren't at the top of my drawing board because I
care mostly for pluggable polymorphic streams (as inspired by java.io
and, in part, GStreamer). However, if they can be integrated without
much hassle, fine.

I'll take a look into your code in a day or two.
Please keep me in touch.
