I'm not certain that you need Boost for this.
streambufs are already designed to buffer information, so simply
providing a large enough buffer for the amount of information
generated on average in the time span you wish between writes ought to
limit writes enough for your application.
The main issue I foresee would be insuring that std::endl isn't used
when you don't want the flush and insuring that the implementations of
your streambufs actually use the buffer as you're expecting.

I can see what you are getting at, but I am not sure that it would give us
everything we need.

For example, if our machine power fails, we have  very limited amount of
battery backup to store everything cached to flash before we run out of
watts, so whatever scheme I implement needs to be able to be told to flush
immediately - can I do that with streambufs?

Hmm. I will look in to it though, as I like the concept.
