         This is a temporary solution but it works.  What you need to do is 
run two instances of Stunnel--one instance configured in client mode and 
the other in server mode.  If you want to run both as services, you can 
install the standard one with the "-install" switch.  For the second 
instance, you need to use some other binary to install it with a different 
name and change the imagepath to point to the executable.
