Yes, that helps!  (Didn't see your response before somehow.)

Plus, following up on my own question, what seems to be needed to share
blobs would apparently be

 0. Have a blob uint8_t ptr [siz]
 1. Create an ETERM for it with erl_mk_binary (ptr, siz)
 2. Send with ei_encode_term
 3. Update refctr / free if needed (docs are not clear)

Sounds like a plan I to try and test.
