Money costs are really not my point - _time_ costs for participants are 
what I'm trying to point to.

My appeal is not "please try to save the LLC money" - its "please be 
sensitive to the impact on your fellow participants".

I pointed perhaps too quickly to just the time impacts in the 
transmission - there's also the storage impacts on the individuals 
(particularly when responses aren't trimmed) times the number of 
subscribers to a given message.
