I'm not sure the best path forward on this, Daniel may have an opinion.  The two options are to implement a new mcstreamer, or to implement a new ".o file" in the assembler backend.  Of the two, I would think the later option is best, but I'm not really sure what it would entail.

No one is working on it!  It would be great for this to start,
