Yes, thanks for the correction. Word8 was a bad choice since endianness is
not an issue.
Thanks for all the advice. It seems I should avoid making my types instances
of Binary. In fact, this relates to another design issue I've been grappling
with, supporting multiple versions of the protocol. Probably I'll need
something like, putProtVersion1, putProtVersion2, etc. Or something along
