Why so? The callback is the standard feature and there are probably hundreds
of applications out there that use it to store the received data in memory
instead of to a file.

That discussion is useful mostly for the less number of copies it would imply
I think. But no, nothing useful did come out of that discussion as of yet and
frankly I have my doubts that it will be possible to do anything like that
nicely without wrecking the internals completely.

But if you're prepared to get your hands dirty and work on it, I'll offer my
ideas, advice and reviews.
