No, you have first go. Dust off your drawing board ;)

Indeed. Well, you can support it anyway by writing a special channel class
for it (or by just using some generic socket channel or whatever)

Roland posted a bit about it, but it all boils down that it is to character
streams what libstore is to block data.
The one thing we need in libchannel we haven't equivalently in libstore is
some way for extending the API on a per-channel-class basis. For example,
for a channel to a sound card raw audio device, you need some way to set the
sample bit rate. For a mouse device you might want to set/clear dtr. For a
keyboard you might want to set/clear raw mode. Etc. Some of this can be
done in the channel class, opaque to the user, but some things can not. I
think the idea was to have dynamically loadable plugins that add this
functionality. But you can probably leave this for later.
Thanks,
Marcus
