Don't shoot the messenger, but I have some bad news for you.  A TCP  
connection (and subsequently an SSL/TLS connection) has exactly two  
endpoints.  You cannot have a connection between a client and "all or  
a subset" of servers.

It looks like you need someone to design a protocol for your specific  
needs.  Such a strange protocol is extremely unlikely to get  
implemented in the official stunnel.

Fortunately stunnel is a free software, so you are free to add  
whatever features you need, or hire someone to do it for you.
