Tom, I admire your optimism about finding competent software and protocol design
people who have awareness of efficiency in this regard. In a world where developers
think a gigabyte-sized 'Hello World' app is OK with drag-and-drop module development
tools, the chances of getting those few bytes of information encoded into less than
several megabytes of cruft included by default by a library the developer has no
knowledge of is slim.
Paul.
