Are there still now platforms where storage bytes are not octets but nonets? i.e. 9-bit based platforms? If so this proposal makes sense, but as a local optimization for these platforms. Problems will code if you want to interchange this data with the large majority of hosts that can handle a 9th bit in their bytes.
Wouldn't these problems mostly be the same as when transferring 8-bit data through old 7-bit systems? This would mean that the various ways of solving the septet/octet problem could equally well be used to solve the octet/nonet problem.
