instead of stuffing all of the i/o stuff into the "kio" library, i've decided to rework i/o to be a generic handler that takes in a function pointer for putc, and does the rest of the logic onto that pointer. That way, you can pass any function that can take in characters and move them to buffers. I'll do a writeup on this at some point to document it.
