Gah. This is what I was looking for. I am not thrilled about exposing
HomeHost to the Internet (ordinarily it would be behind a firewall)
but it looked temptingly close to what I wanted. 

Unfortunately I hit another roadblock in trying this out, which I
think puts an end to this little adventure for now.  But it was an
educational ride. Thanks to everybody for teaching me about SSH

I had troubles seeing how this was different from Richard's solution, 
but now it makes sense. You make the tunnel right from
TargetHost to HomeHost, which is pretty much what I wanted. (Now I
feel kind of silly for not taking the logical step after Richard
proposed his solution). 

I really wish I had not hit that roadblock, because now I am really
curious to see whether this would work.
