I don't know anything about stunnel.  

Why do you think that leafnode wastes bandwidth?  It only downloads the 
groups that you subscribe to.  The first time it is started it needs
the group list, and then it might download the last thousand messages 
of the groups that you select, but that can be configured to a much 
smaller number and it only happens once.

I am not willing to start cutting code, and I used to be a coder.  

A poorly implemented complex design is much worse than a well 
implemented simple design.  Multi-threading rings alarm bells 
in my mind.  If you are confident in your abilities, you are 
very welcome to attempt it yourself.
