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.
