This needs to be done inside the library, rather than be left up to the user, for performance reasons:

File based stream interface keeps a small buffer that it copies bytes into/ writes bytes out of. If we are streaming from a buffer, then there is no need for this small buffer - we can use the input buffer itself for this, and save a memcpy.

This should reduce some of the memory traffic.

HI Aaron,

If I'm not mistaken, you've got an implementation in one of your GitHub branch ? So do I but only for input stream at the moment.

I'm waiting for a full transition to GitHub to do more on this.

Yes, I have an implementation. Let's discuss further when Github transition is complete.
